Question

Proving congruence/// help!! geometry/ trig proof.

Answer 1

E is the midpoint of DF, so point E breaks DF into two equal pieces. Those pieces are DE and EF

Answer 2

do you see what else you can use?

Answer 3

can I prove <DEB is congruent to <FEB if so what postulate would that be

Answer 4

we know DE = EF (from above)

Answer 5

what other segments are congruent?

Answer 6

or BDE, BFE

Answer 7

DA and FC? FB AND DB

Answer 8

i was thinking more like EB = EB (reflexive property)

Answer 9

and then you can use the fact that you have 2 perpendicular segments

Answer 10

I'm still unsure of what postulate to use

Answer 11

do you see how

angle DEB = angle FEB

?

Answer 12

yes

Answer 13

could I use SSS

Answer 14

you use SAS actually (since you have the angle sandwiched between the two sides)

Answer 15

you don't know anything about the third side

Answer 16

why would you need to do that?

Answer 17

thank you
