Question

Are two isosceles triangles an equilateral triangle?

• A. Yes
• B. No
• C. Can't say

Answer 1

The correct option is B No

An equilateral triangle is one, in which all sides and angles, are proportionate. Two isosceles triangles can have, ${30}^{\circ },{30}^{\circ },{120}^{\circ },$ and ${20}^{\circ },{20}^{\circ },{140}^{\circ }$ degrees respectively. An equilateral triangle has all angles of $60$ degrees. So, two isosceles triangles cannot be equilateral.
