In this quick maths article, find out what the angles in a polygon add up to, as well as the difference between interior and exterior angles.
In a right-angled triangle, the two non-right angles are complementary. Why? Because the sum of angles in a triangle is 180°, and one angle is already 90°, the remaining two angles must add up to 90°When two angles add to 90°, we say they "Complement" each other. Complementary...
