Does the fact that YZ = WX lead to the proof that XYWZ is a parallelogram? Why or why not?
A. Yes; all angles will be right angles, and so the sides are parallel.
B. No; both pairs of opposite sides can be congruent without being parallel.
C. Yes; if both pairs of opposite sides are congruent, they must also be parallel.
D. No; opposite angles may not be equal.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
