# B) When the sum of the measure of two angles is 90°, they are calledangles

## Answers

Step-by-step explanation:

1) Vertical angles - (G) are the opposite angles formed by two intersecting lines that are congruent because the angles have the same measure

2)Alternate interior angles: (H) Are formed when a transversal line passes

through a pair of parallel lines and formed on opposite sides of the transversal inside the parallel lines.

3) Corresponding angles: F) Two equal angles on the same side of a line

that crosses two parallel lines and on the same side of each parallel line

4) Exterior angles:(A) Are the angles above and below the pair of parallel lines

5) Supplementary angles:(B) Two angles that have measures with a sum

of 180°

6) Alternate Exterior angles:(D) Are formed when a transversal line passes

through a pair of parallel lines and formed on opposite sides of the transversal above and below the parallel lines.

7) Adjacent angles: (C) are pair of angles that share a vertex and one side but do not overlap

8) Complementary angles: (I) Two angles that have measures with a sum 90°

9) Interior angles: (E) are the angles inside the pair of parallel lines

The answer is complementary angles

Complementary

Step-by-step explanation:

Complementary means that the sum of the angles add up to 90 degrees.
