Question

The reflex angle at each vertex of a triangle is 300 degrees. What is the special name for this triangle?

Answer 1

Given :  The Reflex angle at each vertex of a triangle is 300 Degrees.

To Find : Special name for this triangle  ​

Solution:

Reflex angle  has measure between 180° and 360°.

Sum of angle + its reflex angle = 360°

Reflex angle at each vertex of a triangle is 300°

Hence 300° + angle of triangle at a vertex = 360°

=>  Angle of triangle at a vertex =  60°

Hence Angles at each vertex are 60°

A triangle with all the angles with Equal measures is called Equiangular or Equilateral triangles

Special Name of the  the triangle is Equilateral triangle

Answer:

Reflex angle has measure between 180° and 360°.

Sum of angle + its reflex angle = 360°

Reflex angle at each vertex of a triangle is 300°

Hence 300° + angle of triangle at a vertex = 360°

=> Angle of triangle at a vertex = 60°

Hence Angles at each vertex are 60°
