Geometry is everywhere

SOLID FIGURES Solid figures are 3D figures that have

length, width and heigth. For example :

SphereFaces:0Vertices:0Edges:0

EXAMPLES OF SOLID FIGURES

Cube

Rectangular prism Faces:6Vertices:8Edges:12Conformed by:6 rectangles

Faces:6Vertices:8Edges:12Conformed by: 6 squares

This is a face it is a flat surface, you will found it in solids.

EXAMPLES OF SOLID FIGURES Triangular prism

Cylinder

Faces:5Vertices:6Edges:9Conformed by: 3rectangles and 2 triangles

Faces:2Vertices:0Edges:0Conformed by:2 circles and a curved surface

An edge is a line segment where 2 or more faces meet.

EXAMPLES OF SOLID FIGURES Cone

Square pyramid

Faces:1Vertices:1Edges:0Conformed by: 1circle and a curved surface

Faces:5Vertices:5Edges:8Conformed by: 4 triangles and a square

This is a vertex where 3 or more points meet

This is an equilateral triangle all sides are the same size.

Acute angle is the smallest,it has less than 90 degrees

POLYGONS Polygons are closed figures made up of

lines segments, they are also plane figures.

For example: Triangle

Vertices:3Sides:3

In a scalene triangle all sides have different lenght.

EXAMPLES OF POLYGONS Quadrilateral

Pentagon

Vertices:4Sides:4

Vertices:5Sides:5

Parallel lines never meet

A right angle is a square corner

It is a rectangle it have 4 right angles and is a poligon.

EXAMPLES OF POLYGONS Hexagon

Octagon

Vertices:8Sides:8

Vertices:6Sides:6

Intersecting lines allways cross

Straight angle forms a straight lines.

In this example if the red lines continuous they will Intersect.

CIRCLES Circles are closed and plane figures,

usually it have a center, a chord, a radius and a diameter

For example: CirclesThe chord is a

line segment that connects 2 points of a circle with out passing into the center

The diameter is a line segment that pass into the center and connect 2 points

The radious is a line segment that connects 1 point and the center

The center is a point in the middle of a circle whit the same distance everywhere

SYMMETRY Symmetry is when you divide something

and you get two congruent figures, each the same size.

For example:

Look this figure is congruent.

Look this figure, the sides are not congruent.

SIMILAR FIGURES Similar figures have the same shape

and may have diferent size.

Isosceles triangle have at least 2 sides whit the same length.

CONGRUENT FIGURES AND MOTIONS

Congruent figures and motion is when you slide, flip or turn a figure.

Slide:is when you move figure in a straight direction.

It is a square all sides have the same length and it have 4 right angles

SOME WAYS TO MOVE A FIGURE

Flip: its the reflection of a figure that gives its image like a mirror

Turn:make a figure move about a point.

It is a trapezoid have one pair of parallel lines.

LINES Lines go in 2 directions and it is a

straight path of points. For example

Intersecting lines

Obtuse angle is grater than 90 degrees

MORE LINES Perpendicular lines are lines that form

right angles

Line segment have 2 endpoints also is part of a line.

MORE LINES A ray

point

A point is an exact location in space

A ray is a part of a line, and it goes in 1 direction.

MORE LINES Angle

It is made by 2 rays whit the same endpoint.
