<span>Quick Check: Review of Parallel and Perpendicular Lines
1. B. angle 4
2. B. </span>alternate interior angles<span>
3. D. 150
4. </span>D. a = 36, b = 118, c = 62
The answer should be 19 if you mean 3 to the power of 2. as listed below.
These bisectors intersect each-other at 90 degrees. And it means that they are perpendicular. Since they are perpendicular, we find that there 4 congruent triangles and XY is parallel to WZ and WX is parallel to YZ. Additionally, opposite angles are equal. These two latter findings are the characteristics of the parallelogram.
