Question

Assume ABC DEF. If AB = 12, BC = 15, and AC = 17, what is the length of EF

Answer 1

EF=15

Explanation:

The legth of EF is the same as BC because both of these segments come at the end. For these sort of problems, you need to match up the line segments/angles on both sides of the equal side. For example, the line segment AB will be the same as DE because they are both in front of the equation on both sides. Hopefully this makes sense :)

Answer 2

If it's just like the last one, then 15 because in my head abc can equal 123 and def = 123 so 23 = 15. If that makes any sense lol
