Maths Triangle

 Triangle Facts 

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side. 2D shape properties – Different Types of Triangles.

1. Different type of triangles 

Right triangle - A right triangle is a triangle in which one of the angles is 90 degrees.

Obtuse Triangle - Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. 

Acute triangle - An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees

Equilateral triangle - In an equilateral triangle, all the lengths of the sides are equal. In such a case, each of the interior angles will have a measure of 60 degrees. 

Isosceles triangle - In an isosceles triangle, the lengths of two of the three sides are equal. So, the angles opposite the equal sides are equal to each other. 

Scalene triangle -  A  scalene triangle has all side lengths of different measures. No side will be equal in length to any of the other sides in such a triangle.
