Think & Click: Supplementary and Complementary Angles
Now, you try. Complete the Think & Click activity by looking at each problem below, thinking about it, and then clicking on the question to reveal the solution.
If angle A measures 28° and angle B measures 61°, are angles A and B complementary? Why or why not?
No. 61 + 28 = 89°, not 90°.
If angle H measures 109° and angle J measures 71°, are angles H and J supplementary?
Yes. 109 + 71 = 180°, therefore they are supplementary.
If angle L measures 32°, what would angle T have to measure for it to be complimentary?
58°. 32 + x = 90, x = 58.
If angle N measures 93°, what would angle K have to measure for it to be supplementary?
87°. 93 + x = 180, x = 87
