Two angles are complementary if their sum equals exactly 90 degrees. Two angles are supplementary if their sum equals exactly 180 degrees, so a 30 degree angle is supplementary with a 150 degree angle.
An angle is not normally defined by two characters. Also, a rhombus cannot have two angles whose measures are 14 and 17: any two angles MUST be complementary or equal.
The sum of the two angles is 360. So angle ABC = 120 degrees.
The sum of two supplementary angle equals 180 degrees.
No. Supplementary angles are angles that add up to 180˚. One straight angle already equals 180˚. Two straight angles add up to 360˚.
96˚all angles to a triangle equals 180˚
No. That is true only of a 90° angle.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
It is to bisect the angle into two equal angles.
Mathematically - A regular pentagon has interior angles and sides equal. Bisecting each interior angle and extending a line segment to the center gives you five equal angles (360o/5=72o). Using the triangle formed by two line segements and a side of the pentagon we know the sum of interior angles of each triangle equals (180o) and we know one angle is 72o. The sum the other two interior angles of each triangle equals (180o-72o=108o) which equals each interior angle of the pentagon (equal to the sum of these two angles). Thus the exterior angle of each corner of the pentagon equals (360o-108o=252o). :-)
