(b) true

(c) true

(d) false

(e) false

(f) true

2. (a) correct

(b) correct

(c) correct

(d) correct

(e) correct

(f) correct

(g) correct

(h) correct

(i) Incorrect. correct answer would be alternate interior angle converse theorem

(j) incorrect, <1 and <2 are a linear pair

Since p and q are parallel and <1 = 125.

<1 and <3 are a linear pair, that is <1+<3 = 180 or <3 = 180-125 = 55

<3 = <6 = 55 (Alternate interior angles)

<1=<4 = 125 (vertical angles)

and <4=<5 =125 (alternate interior angles)

As far as the true/false and correct/incorrect part of the assignment, you have done a great job, clearly showing an understanding of angles. Good job.
