Given △abc with ad¯≅db¯, ae¯≅ec¯, de=4 cm and you know that de¯ is a therefore, bc= cm.

DE is a midsegment, and BC= 8cm. It should be written as: midsegment, 8

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
