Question

In an equilateral triangle, the measure of each angle is .

Answer 1

In an equilateral triangle, all sides and all angles are equal.

We also know by angle sum property that the sum of the angles of a triangle are equal to ${180}^{\circ }$.

Let the measure of every angle of the equilateral triangle be $x^{\circ }$

$x+x+x={180}^{\circ }$
$\Rightarrow 3x={180}^{\circ }$
$\Rightarrow x=180÷3$
$\Rightarrow x={60}^{\circ }$
