Can someone do this for me please. I don’t understand.

1. B
2. A
3. true, false, true
4 and 5. i’m not really sure about these sorry
6. C

Explanation:

1. Angle 2 and angle 7 are alternate exterior angles, not alternate interior angles.

2. Supplementary means the sum of the angles is equal to 180° and angle 1 and angle 7 have a sum of 180°.

3.
a. One way to solve this is if you look at angle 1 and 5, you can see they are corresponding and have the same angle. If angle 3 and angle 1 form a straight line (180°) that means that angles 3 and 5 will also equal 180°.
b. Angle 2 and angle 6 are both alternate exterior angles and have the same angle measure, so their sum will be greater than 180°.
c. Angle 8 and angle 1 are alternate interior angles and have the same angle measure.

6. So we know that the sum of the 3 interior angles of a triangle = 180°. The 2 angles given are 40° and 80°, which gives us a sum of 120°. To get to 180°, the last angle, angle c, must be 60°. Therefore, C is correct because it includes the angles 80° and 60°, which leaves the last angle to be 40° and therefore completing the triangle.

i hope this was helpful! plz mark brainliest :)
