What kind of angles have their sum of measures equals $180 ^ { \circ }$?
A) supplementary
B) complementary
C) acute
D) vertical
E) right

Question

Quizplus · Accepted Answer

Supplementary angles are two angles whose measures add up to 180 degrees. Therefore, their sum of measures equals 180 degrees. Complementary angles have measures that add up to 90 degrees, so that is not the correct answer. Acute angles are less than 90 degrees, so their sum could not equal 180 degrees. Vertical angles are a pair of non-adjacent angles formed by two intersecting lines, and their measures are always equal but not necessarily add up to 180 degrees. Right angles are angles that measure 90 degrees, so their sum of measures could not equal 180 degrees.
