Question

In the adjoining figure, AB/CD are cut by a transversale at E and F respectively.
angle 1 +70°, find the measure of each of the remaining marked angles.​

Answer 1

• 1 = 70
• 1 = 3 ( vertically opposite angles)

70 = 3

• 1 + 2 = 180 ( linear pair )

70 + 2 = 180

2 = 180 - 70

2 = 110

• 2 = 4 ( vertically opposite angles )

110 = 4

• 3 = 5 ( corresponding angles )

70 = 5

• 6 = 4 ( corresponding angles )

6 = 110

• 6 = 8 ( vertically opposite angles )

110 = 8

• 5 = 7 ( vertically opposite angles )

70 = 7

hope this is helpfull
