Question

Show that the angles of an equilateral triangle are 60°

Answer 1

Equilateral triangle has all sides equal.For triangles sum of interior angle=180degrees
since for equilateral all sides are equal then let x represent the sides
$x + x + x = 180deg$
$3x = 180$
$x = \frac{180}{3} = 60$
hence angle of equilateral triangle is 60
