Complementary and Supplementary Angles — Unit test Answers

A line contains points F, G, H, I, J. The space between F G is 2. The space between H and I is 1. The space between F and I is 7.

Horizontal lines e and f are cut by vertical lines a and b. At the intersection of lines a and e, the uppercase right angle is (x + 1) degrees. At the intersection of lines a and f, the bottom right angle is (x minus 3) degrees. At the intersection of lines b and e, the bottom left angle is y degrees.

Point G lies between points F and H on .

Lines a and b are parallel lines cut by transversal f.

In which diagram do angles 1 and 2 form a linear pair?
