Converse of the corresponding angles postulate
Explanation:
The corresponding angles postulate says that if we have two parallel lines, then the corresponding angles are congruent.
The converse of this is where we go in reverse: if we know the corresponding angles are congruent, then the lines are parallel.
Corresponding angles are ones where they are on the same side of the transversal line, and also on the same side of each adjacent parallel line. In this case, the angles 52 are to the right of the tranversal, and each are above their neighboring parallel line. We could say the two corresponding angles are both in the upper right hand corner (think of the two lines crossing to form 4 corners or regions)
Ответ:
Since these pools are similar, they have a scale factor that determines the ratio between each of the sides.
VR = 12
BF = 4
12 / 4 = 3
The scale factor = 3
WZ and TM are similar sides so,
7 * 3 = 21
a = 21
