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.

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.
