Advertisements
Solution
Measures of each of the angles of an equilateral triangle is 60°.
Explanation:
Measures of each of the angles of an equilateral triangle is 60° as all the angles in an equilateral triangle are equal.
Let x be the angle of the equilateral.
According to the angle sum property of a triangle,
x + x + x = 180° ...[∵ Measure of each angle = x (say)]
⇒ 3x = 180°
⇒ x = `180^circ/3`
⇒ x = 60°
