INTERMEDIATE LEVEL 7. Devi folded a sheet of paper into an envelope, as
shown in the figure. In the figure, ZAED = ZADB
= ZBCD = 90°. To seal the envelope, she has to
apply glue along AD and DB. Given that AE = ED
= 8 cm and DC = BC = 14 cm, find the total length
of the sides along which the glue has to be applied
to seal the envelope.

Me! i'm really confused the isosceles trapezoids, abcd and efgh, are similar quadrilaterals. the scale factor between the trapezoids is 2: 3, line gh = 6 centimeters, line ad = 8 centimeters, and line ab is three times the length of line dc . use complete sentences to answer the following prompts and include all of your calculations in your final answer. a. write a similarity statement for each of the four pair of corresponding sides. b. write a congruence statement for each of the four pair of corresponding angles. c. determine the perimeter for each of the isosceles trapezoids.
