Question

Each angle of an equilateral triangle measures ________ .

• A. ${40}^o$
• B. ${50}^o$
• C. ${60}^o$
• D. ${70}^o$

Answer 1

The correct option is C ${60}^o$

In an equilateral triangle, all the angles are equal.

$\text{We know that sum of the angles of a}\text{triangle is}{180}^o.$

$\text{Let each angle of an equilateral}\text{triangle measure}x.$

$\text{Then,}x+x+x={180}^{o}3x={180}^{o}x=\frac{{180}^o}{3}={60}^o$

So, each angle of an equilateral triangle measures ${60}^o$.
