Answer 1 Angle 1……Symmetric Answer 2 AB = TU ……...

Students will analyze & apply properties of special pairs of angles to solve angle diagrams. Why? So you can describe angles in a home, as seen in Ex 44. Mastery is 80% or better on 5-minute checks

 Complementary Angles- A pair of angles whose sum is 90.  Supplementary Angles- A pair of angles whose sum is 180.  Linear Pair- A pair of adjacent angles whose sum is 180.  Vertical Angles- Two Angles whose sides form opposite rays.

Angle 3 = 112, Angle 2 & 4 = 68 Angle 4 = 67, Angle 1& 3 = 113 Angle 2 = 71, Angle 1&3 = 109

X=5 & Y=26 Angles are 74 & 106 X=10 & Y=40 Angles are 130 & 50

X = 7 and Y = 9……so Angle Measures are 36 and 144
