In the diagram ABCD EFCH A Which angle in EFCH is congruent

In the diagram. ABCD - EFCH. (A) Which angle in EFCH is congruent to

Solution

ABCD~EFGH

A. \'F\' angle is congruent to \'B\'

B.Scaling factor = 12/20=3/5

C. 12/30=x/15 =>x=9

D. 15/Y=12/20

=>Y= 25

E.perimeter of EFGH= 85

Hence perimeter of ABCD=85*3/5=51

F. If AC= 18

Then EG= 18*5/3=30.
