This document discusses different types of angles found at a house including obtuse angles that are greater than 90 degrees, acute angles that are less than 90 degrees, vertical angles that are opposite angles formed when two lines intersect, straight angles that are 180 degrees, a linear pair that are two angles whose non-common sides form a line, a right angle that is exactly 90 degrees, a bisected angle that is cut into two equal parts by a transversal, complementary angles whose measures add up to 90 degrees, and supplementary angles whose measures add up to 180 degrees.
