132. In a triangle, all sides are equal. Find its angles.
$\Delta$ An equilateral triangle (in which all sides are equal) is a special case of an isosceles triangle, and any side can be taken as the base. Therefore, all angles in it are equal. Since the angles sum up to $180^{\circ}$ (from the previous problem), each of them is $60^{\circ} . \triangleleft$
