Find the unknown angle measurements. Then write your reason of why it is that angle and it has to be theorems or postulates. Ther are some filled out so fill the others in angle 1. 90° - alternate interior, everything in the square box is 90° and angle 1 is across angle 8 which is 90°
angle 2. 90° - linear angle, angle 2 is opposite of the 90° box
angle 3.
angle 4.
angle 5.
angle 6.
angle 7.
angle 8. linear angle, is opposite from angle 21
angle 9.
angle 10.
angle 11.
angle 12.
angle 13.
angle 14.
angle 15.
angle 16.
angle 17.
angle 18.
angle 19. 90° - verticle to the right angle
angle 20.
angle 21. 90°- linear angle, opposite of angle 8
angle 22. 90°- linear angle, opposite to angle 26
angle 23.
angle 24.
angle 25. 78° -linar to angle 102 degrees 190-102=78
angle 26. 90° - because it is on top of angle 22 so it is a linear angle
angle 27.​
