Final answer:
In a parallelogram, opposite angles are congruent.
Step-by-step explanation:
a) To find the measurement indicated in the parallelogram of 90°, we need to look at the angles of the parallelogram. In a parallelogram, opposite angles are congruent. So, if one angle is 90°, then the opposite angle must also be 90°.
b) Similarly, if the measurement indicated in the parallelogram is 95°, then the opposite angle must also be 95°.
c) For the measurement indicated as 125°, the opposite angle will also be 125°.
d) Finally, if the measurement indicated is 50°, then the opposite angle will also be 50°.
