# GEOMETRY

### what is it??

## ANGLES

**.**

*well as you know and probably heard there are four types of angles ACUTE,RIGHT,OBTUSE,AND STRAIGHT. so what do these angles look like? well i´ll show you*## PROTRACTOR

*what's a protractor you ask? well,it's the tool you use to measure all those types of angles from acute to straight.it's kind of like a ruler in some ways, but the way you use it is you put the little hole in the middle on the vertex, then you line up the end along one ray, measure it and there you go you just used a protractor.*## Triangles

*there are ,just like angles, different types of triangles like..* ## RIGHT TRIANGLEthis is a right triangle the little box in the corner means the angle measures 90 degrees. | ## ISOSCELES TRIANGLEthis is a isosceles triangle, the lines on the side mean that those angles measure the exact same degree. | ## OBTUSE TRIANGLEthis is a obtuse triangle you can tell because it only has one obtuse angle |

## RIGHT TRIANGLE

this is a right triangle the little box in the corner means the angle measures 90 degrees.

## ISOSCELES TRIANGLE

this is a isosceles triangle, the lines on the side mean that those angles measure the exact same degree.

*there are more than this but i didn´t fit them all the other types are scalene,equilateral,and acute.some of them have the names of angles and that´s because they have those angles in them.*## QUADRILATERALS

*quadrilaterals are four sided figures. most of the time the angles are all right angles. there are many different types like rectangle,square,polygon,parallelogram,trapezoid,and a rhombus.* ## SQUAREthis is a square all sides are congruent,opposite sides are parallel,all angles are 90 degrees. | ## RECTANGLEthis is a rectangle it's the same as a square the angles, the sides a square is a rectangle. | ## RHOMBUSthis is a rhombus it's a 4 sided polygon,all sides are congruent,opposite angles concruent |

## SQUARE

this is a square all sides are congruent,opposite sides are parallel,all angles are 90 degrees.

## RECTANGLE

this is a rectangle it's the same as a square the angles, the sides a square is a rectangle.

## FUN WITH GEOMETRY

*okay some people ( lots of people ) say they don´t like geometry, well there are fun things to do with it like just look at this.they wrote a song about it.*
