4. C)If two figures are congruent, then they are similar. If they are congruent them shape and size are the same and hence they are similar
5. Ratio 4/3 smaller side is 21 Multiply to find large side 4/3×21= 28ft D)
6. Width went from 24 to 3 in divide to get ratio 24/3 =8 now divide the length by 8 to find the postcard length 32/8= 4 in A)
8. If they are similar you need to find the ratio y reduces from 8 is similar to 6 so link those 6/8 This is your ratio you can simplify it to 3/4 now y/6 should also = 3/4 Y/6=3/4 Y=18/4= 4.5 C)
For number four, the correct answer is C) If two figures are congruent, then they are similar. Because congruent is where two angles are the exact same degrees!
For number five, the correct answer is D) 28 feet because for every three feet on the short side, there is four feet on the long side. If the short side is 21 feet it was three times SEVEN, therefore you have to multiply seven to the long side as well and you get 28 feet!
For number six, the correct answer is A) 4 in because it was 24 then it went to three, so divide those two and you get four!
For the number eight, the correct answer is B) 6 because the sides are the same, so look at the left one to find the matching sides!
For the number nine, the correct answer is C) DC because the sides are the same, so if the answer to the smaller one is the base, the bi gger one has to be the base as well, which is DC!
Because the number of sides is 6 so the s go interior angles is 720. So if u want to get x u need to sum up the rest of the angles anf subtract from 720 giving an answer of 130
