It is the place where there are two lines, the origin or the end of a straight line, the center of an arm or that of a tiny circle. Obviously it does not have dimensious and is designed by a capital letter or by a number.
A,B,C....1,2,3....

LINE

It is a sucession of points. It is nameb by a small letter, a,b,c...

There can be several types of lines:

STRAIGHT LINES

It is a sucession of points in the some directions, It has neither beginning nor end. It can be horizontal, vertical or oblique. It is named by small letter.

LINE CURVE

It is a sucession of points not planes in the same directions.

POLYGONAL LINE
It is composed by straight segments joined by his ends in different directions. The segments are called sides, and the common points to two consecutive sides are named vetices.

HORIZONTAL LINE

Straight line that coincid with the direction of the lines of the horizon, so that all the points have the some level.

VERTICAL LINE
Straight line that coincid with the direction of all the bodies on having fallen down, remaining represented by the direction of the thread of a plumment.

SLOPING LINE
Any straight line that is neither horizontal or vetical.

PERPENDICULAR STRAIGHT LINES

They are those that, on having be cut, the divide to the plane in four right angles (90o)

PARALLEL STRAIGHT LINES

They are those that follow the some direction and, therefore, thought they should extend, they never manage to be cut.

COMPETING STRAIGHT LINES
Those are not parallel bars; therefore they are cut in a point.

ANGLE

It is the opening between two lines that come together at a point or vertex.
An angle is possitive when it measures up in sense of travel opposite to the needles of the clock, in opposite case it is negative. While the opposite is not indicated, of both convez angles and concave that they define two half lines that depart from the some point, it is considered to be the mirror of them; this is the convex angle.

OPENING OF THE ANGLE

The angles measure uo in degress sexagesimales.Every degree it has 60 minutes and every minute has 60 seconds.

-We can classify the angles acording to the opening that they present:

RIGHT ANGLE
The one that measure 90o

OBTUSE ANGLE
The main of 90o

SHARP ANGLE
Less than 90o

FLAT ANGLE
Each of the semiplanes limited by two opposite half lines.

-If we abide ourselves by the position that they have between them, the angles can be:

CONSECUTIVE ANGLES

They are those who the some vertex and a common side. Also they name continuous.

ADJACENT ANGLES

They are those consecutive angles which not common sides are straight line. His sum costs two right angles (180)

ANGLES OBJECTED BY THE VERTEX

Those in which each one is formed by the prolongation of the sides of other one. The angles objected by the vertex are equal.

SUPLEMENTARY ANGLES
Those that added cost plain, that is to say, two right angles (180).

CIRCUNFERENCE

It's the closed and flat line, in that all his points equidistants of other fix (0) called center.

LENGTH OF A CIRCUNFERENCE

Distance that is crossed on having moved on the circunference, returning to the some point.The circunference has 360o

RADIUS

Distance of the pionts of the circunferencen to the center or of the someone.

ARCH

Part of the circunference included between two ponits.

SEMICIRCUNFERENCE

Arch that corresponds to half a circunference

CENTRAL ANGLE

The formed for two radious.

ROPE

Denomination that is given to any segment that joins two points of the circunference.

DIAMETER

Rode that passes for the center of the circunference, the diameter is the bigest rope string and costs two times the radius

DRYING

Straight line that cuts to the circunference in two parts

TANGENT

It is any straight line that touches to the circunference in a point and only in one.

SEMICIRCLE

The half of a circle.

CIRCULAR WREATH

Partion of limited surface for two concentric circunferences.

LUNULA

Intersection of two circles. It is the surface that two dying circunference limit.

SEGMENT CIRCULAR

Portion of a circle limited by an arch and the corresponding string.

WRAPS CIRCULAR

Portion of circle limited by two parallel string

CIRCULAR SECTOR

Portion of circle included between two radius and they included.

MEDIATRIZ OF ONE SEGMENT

Staight line perpendicularto this one for his average point.

BISECTRIX OF ANGLE

Straight line that happens fos his vertex and divides it in two equal parts.

PLANE

Three not aligned points, or two straight lines that are cut, define a plane.

TRIANGLE

They are flat figuers limited by three straight lines that cut two to two. The points where they are cut are called vertexes and segments that join them are named sides.

Acording to this we can classify them in:

-EQUILATERAL TRIANGLE

It is that one that possesses tree sides of the same sizes.

-ISOSCELES TRIANGLE

It is that posseses two sides of equal size and unequal one

-TRIANGLE SCALENE

It is that posseses two sides of equal size and unequal one

Acording to his angles the triangles can qualify in:

ACUTE-ANGLED

All his angles is main of 90
o

OBTUSE-ANGLED

One of his angles measures more than 90
o

RECTANGLE

One of his angles measures 90o

QUADRILATERAL

They are flat figures limited by four that cut two to two, determining a few segments that are the sides of the quadrilateral one. The points where two contiguos sides meet are the vertexes in the quadrilateral ones there appears the diagonal segment that joins two not consecutive vertexes.

The quadrilaterals can quialify in:

PARALLELOGRAMS:

The sides are parallel two to two .
-Square: It is that one that has four sides and four angles.
-Rectangle: It is that one which four sides have the same length.

RHOMBUS

The rhombus is a polygon of four equal sides, but his four angles are different from 90o. The area of this figure is calculated by means of the formula: A= long diagonal x minor diagonal 2

ROMBOIDE

A romboide is a parallelogram that has opening sides and angles equal. A= base · height

TRAPEZE

The trapeze is a polygon of four sides but his four angles are different from 90o. The area of this figure is caculated by means of the formula: A= [(major base + minor base) · height]
2

- RECTANGLE TRAPEZE

The rectangle trapeze is that one in which one of his angles measure 90o.

-ISOSCELES TRAPEZE

The isosceles trapeze is that has two not paraller equal sides.

OVAL

The oval is a closed and plane curve, composed for four circular arc equal two-two. It have two axis of the symetry perpendicular each other.

OVOID

The ovoid is a closed and plane curve, composed for two circular arc equal and other twop unequal, it have a single axis of symmetry.

SPIRAL

The spiral is an open and flat curve generated by a point moving uniformly along a line, while this revolves around one end with constant angular valocity.

SCROLL

The scroll is a open and flat curve, composed by circular arc linked toguether, whose venters are the vertexs of a regular polygon: a triangle, a square..., called core.

It is the place where there are two lines, the origin or the end of a straight line, the center of an arm or that of a tiny circle. Obviously it does not have dimensious and is designed by a capital letter or by a number.POINTPOINTtoc
