Is it a parallelogram if the diagram shows one pair of congruent sides and one pair of congruent angles?
I was taking a test today and I was confused on this problem. The test showed me a picture that showed a what seemed to have looked like a parallelogram but with one pair of opposite congruent sides and another pair of opposite congruent angles. The answer choice was between,
Yes- this is a parallelogram because it meets a condition
No- this is not a parallelogram because it does not meet the conditions
It takes awhile to see this, but apparently the answer is no. The problem is that you can add a diagonal to break the quadrilateral into two triangles, then establish SSA congruence using the two angles, the opposite sides, and the diagonal common to both triangles. However, SSA congruence is not enough to establish congruence of the two triangles, which means you can't prove the other two sides are equal. So, you don't know for sure you have a parallelogram.
