Answer 1

@Extraordinaire plz plz help me I will give medal

Answer 2

This should be easy, it would be difficult to write a paragraph about it though

Answer 3

have you learned about postulates yet?

Answer 11

any time ^u^ if you need anymore help on postulates heres a sketch of my lecture notes in case you run into any trouble.

corresponding angles: 1 and 5
vertical angles: 2 and 3
alternate interior angle: 4 and 5
alternate exterior angle: 2 and 7
consecutive interior angle: 3 and 5

Answer 12
