11. If Angle 2 = 100°, then Angle 1 = 80°
Explanation: Angle 1 and 2's measurements SHOULD be 180° if they are added up. If Angle 1 is 100°, then: 180 - 100 = 80
12. If Angle 1 = 55°, then Angle 4 = 125°
Explanation: Angle 1 and 3 & Angle 2 and 4 have @"equal measurements: 180 - 55 = 125°, this means Angle 2 is 125°, therefore, Angle 4 is also 125° because their measurements SHOULD ALWAYS be the same.
13. If Angle 4 = 123°, then Angle 3 = 57°
Explanation: 180 - 123 = 57°
