Question

Measures of each of the angles of an equilateral triangle is ___.

Answer 1

The angle of the Equilateral triangle.

An equilateral triangle is one whose all sides and angles are equal.

Let the angle of the equilateral triangle be $x°$ and since the sum of the angle of a triangle is $180°$ [Angle Sum Property]

Therefore,

$\begin{array}{rcl}x+x+x& =& 180°\\ & \Rightarrow & 3x=180\\ & \Rightarrow & x=\frac{180}{3}\\ & \Rightarrow & x=60°\end{array}$

Hence, Measures of each of the angles of an equilateral triangle is $\underline{60°}$.
