Question

Which pair of angles must be supplementary

Answer 1

D.) 6 and 2

Explanation:

Supplementary angles are two angles which sum up to 180°.

Answer 2

B.
`\angle 2\text{ and }\angle 5`

Explanation:

We have been given an image of intersecting lines. We are asked to find the pair of angles that must be supplementary.

We know that two angles are supplementary when they add up-to 180 degrees.

Upon looking at our given image, we can see that the measure of angle 2 and measure of angle 5 is 90 degrees. So these angles will add up-to 180 degrees, therefore, option B is the correct choice.
