Question

Is the length of DE is shown, what other length can you determine for this diagram? Help me please

Answer 1

Another length of this diagram FE=12.

Step-by-step explanation:

According to diagram

In triangle FED, EM is perpendicular bisector of FD.

In ΔFED, EM ⊥ FD and FM=MD

In ΔFME and ΔDME

FM=DM (Given)

∠FME=∠DME (each 90°)

ME=ME (Common)

ΔFME ≅ ΔDME (By SAS congruence property)

Therefore, FE≅DE (by CPCT)

But DE=12

So, FE=12

Thus, Another length of this diagram FE=12.
