Question

exit ticket (day 1)
use the figure.

1. ∠1 and ∠___ are complementary angles.
2. ∠5 and ∠___ are supplementary angles.
3. ∠1 and ∠2 are/are not a linear pair of angles?

Explanation:

Step1: Recall complementary angles

Complementary angles add up to 90°. In the figure, ∠1 and ∠2 are complementary since they form a right - angle.

Step2: Recall supplementary angles

Supplementary angles add up to 180°. ∠5 and ∠6 are supplementary as they form a straight - line.

Step3: Recall linear - pair of angles

A linear pair of angles are adjacent and their non - common sides form a straight line. ∠1 and ∠2 are not a linear pair as their non - common sides do not form a straight line.

Answer:

1. 2
2. 6
3. are not
