2 Supplementary and omplementary ngles When the two sides of an angle form a straight line, the angle is called a straight angle or flat angle. Specifically, the angle is measured to be o Honors Geometry Issue [Linear Pair Postulate] Two angles of a linear pair are supplementary to each other.. What should be the value of x in the figure? x 0 o Straight angle is 80. Right angle is 90. right angle notation, it stands for 90 o right angle is special, it also has a special notation. Instead of writing 90 at the angle, we draw a small square near the angle vertex. oth and are right angles in the figure. Each angle of a rectangle is a right angle. 90 o 90 o 90 o If the sum of two angles is 90, we called them complementary angles. Namely, + = 90 and are complementary. If the sum of two angles is 80, we called them supplementary angles. Namely, + = 80 and are supplementary.

16 Honors Geometry Issue nswer Key Supplementary and omplementary ngles. x +0 = 80 x = 30. Vertical ngles. vertical: 4 adjacent: 3. Vertical angle pairs: (, 4), (, ), ( 3, 6). djacent pairs (, 6), ( 6, ), (, 4), ( 4, 3), ( 3, ), (, ) = 7 since and are linear pair with respect to line M = 0 since and 3 are linear pair with respect to line L. 6. vertical angles congruent = = 7 for vertical angles. 8. Yes, it is always true The angle is 30 since 9060=30. Therefore, its supplementary angle is = The complementary angle for 60 is ivide 80 into + parts. Each part gets 60. The angle in the question should get two parts, thus it has The complementary angle for 4 is still The complementary angle of 3 is. The supplementary angle of 3 is The complementary angle of 40 is 0. The angle is two times 0, so it must be 00.. = 4, (vertical angle) 4 = 3 (given) 3 = (vertical angle) = (transitivity) = 90 (Given) = 0 = + (angle addition property) = = = = 3 since the bisector divides the right angle to two angles with x = + 3x x = x 0 = 4x x = = (60  x) = 6
