I need help fast. If each interior angle of a regular convex polygon is three times the measure of each exterior angle, what kind of polygon is it? A baseball diamond’s home plate has three right angles. The remaining two angles are congruent. What are their measures?

    Since the interior and exterior angles add up to 180 degrees, the exterior angle is therefore 1/4 of 180=45 degrees. The sum of all exterior angles of a regular polygon is 360 degrees, so the number of sides can be obtained by division of 360 by 45.
