Draw two rectangles. the first has a length of 9 cm and a width of 18 cm. the second has a length of 27 cm and a width of 54 cm. come up with two different ways to prove that these rectangles are proportional or not.

show your work.

1. 2. ∠b and ∠y are right angles. 3.? 4.? which two statements are missing in steps 3 and 4? ∠x ≅ ∠c △abc ~ △zyx by the sas similarity theorem. ∠b ≅ ∠y △abc ~ △zyx by the sas similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem.
