Write a note on the introduction to triangles.

Answer 1

Note on the introduction to triangles :

A triangle is a three-sided polygon with three vertices. It’s the simplest polygon with the least sides. The sum of the interior angles of a triangle is equal to $180°$.

Types of triangles :

The triangle is classified into the following categories based on the length of its sides:

Scalene Triangle		All the sides of a triangle having different side measurement
Isosceles Triangle		Two sides of a triangle are of the same measure
Equilateral Triangle		All three sides of a triangle having equal side measurements

Triangles are further categorized based on their angles.

Acute Angle Triangle		All the angles of a triangle are less than 90 degrees
Obtuse Angle Triangle		One of the angles of a triangle is greater than 90 degrees
Right Angle Triangle		One of the angles of a triangle is equal to 90 degrees

Thus, a triangle is a three-sided polygon with three vertices. It’s the simplest polygon with the least sides. The sum of the interior angles of a triangle is equal to $180°$.
