Question

The two figures above are congruent. Find the measure of the angle that isn't labeled on either figure.

Answer 1

Since the two shapes above are congruent, meaning they are the same, you can observe that three of the four angles for the total shape are given. The angles that were given include 133, 86, and 41 degrees. However, a quadrilateral has 360 degrees, and you can find the missing angle by adding up the three given degrees and subtracting it from 360. 133+86+41=260 degrees. You can then subtract it from 360. 360-260=100. So, the degrees of the missing angle is 100 degrees.
