Calculate the number of sides of a regular polygon whose interior angles are each 156 degrees?
Exterior angle = 180-156 = 24 degrees Number of sides = 360/24 = 15 sides. If you can't remember the formula, then remember this to help figure it out: The regular polygon can be divided into triangles (like pizza slices). Each triangle is an isosceles triangle and all of them are congruent (since it's a regular polygon). Take one of the triangles: each of the 'leg angles' will be half of the polygon angle (the leg of the triangle has bisected the polygon angle). So these two angles will add together to be the same measure as the polygon angle (call it Ap). So the other angle in the triangle is in the center and all these pizza slice angle make a circle in the middle (360°). Since the triangle sums to 180°, the angle in the middle is (180° - Ap), then you have: Number of sides = (360°) / (180° - Ap), or in this case: 360/(180-156) = 15 sides.
How do you describe an acute angle?
It is an angle more than 0 degrees but less than 90 degrees. An acute angle is any angle of between 0 and 90 degrees. A right angle is an angle that measures exactly 90 degrees. An obtuse angle is an angle that measure between 90 and 180 degrees. To remember the difference between an acute angle and an obtuse angle, think of "a cute" (acute) puppy and an large obese (obtuse) bulldog. Kind of cheesy but the words do sound alike and might help you remember
When is supplementary?
Supplementary Angles are two angles that add up to 180 degrees. Often you can find them on a straight line, however, they don't always have to be together. There is a related link that can help explain.
Two angles whose sum is 90 degrees?
two angles whose sum is 90 degrees is a complementary angle.

Can someone help you learn how to find the measures for complements or supplements and vice versa?
Complementary angles: Two angles that add up to a right angle (90°). Each angle is complement of the other.For example, the complement of a 30° is 60° (90° - 30°).Supplementary angles: Two angles that add up to two right angles (180°). Each angle is supplement of the other.For example, the supplement of a 30° is 150° (180° - 30°).
