INTRODUCTION

Geometry, branch of Mathematics that deals with shapes and sizes.Geometry may be thought of as the science of space.Just as Arithmetic deals with experiences that involve counting, so geometry describes and relates that involve space.Basic geometry allows us to determine properties such as areas and perimeters of to dimensional shapes and the surface areas and volumes of three-dimensional shapes. Triangles are the part of Mathematics.Triangles are very useful to us.Here,we are starting a study about triangles.

AIMS

To know about triangles

To understand the usages of triangles

To understand the theorems about triangles

To study the angles of triangles

To study the sides of triangles

METHOD OF STUDY

We collected information from our previous test books

We asked to others to know more about triangles

We collected data from internet

We depended our teachers

DATA COLLECTION

Step-I

First Glance

A triangle is the simplest polygon,having three sides and three angles.The sum of the three angles of a triangle is equal to 180 degrees.

Triangles are classified by sides and by angles.

Triangles

Classify triangles

By sides

a bIsosceles 2 equal sides side a=side b

Acute 3 acute angles

By angles

Scalene no equal sides

Obtuse 1 obtuse angle

a b

c

Equilateral 3 equal sides a=b=c.

Right triangle

Analysis

Triangles are classified in two general ways, by their sides and by their angles.First, we will classified by sides.

Conclusion

Through this project, we got so many informationes about triangles.There are three angles in a triangle.The sum of three angles are 180 degree. We selected three triangles for study. They are isosceles, acute and right triangles.We could understand all the features of these triangles.This is a very useful project to us.
