PLEASE HELP!!!!!!!!!!!!! Choose the abbreviation of the postulate or theorem that supports the conclusion that the triangles are congruent. Given: C, F are rt. 's; AB = DE; BC = EF HL LL HA LA

OpenStudy (anonymous):

like Taylor Swift?

OpenStudy (anonymous):

nah to country

OpenStudy (countrygirl1431):

what?

jimthompson5910 (jim_thompson5910):

is there a diagram of this?

OpenStudy (countrygirl1431):

yea hold on

OpenStudy (countrygirl1431):

jimthompson5910 (jim_thompson5910):

oooh ok, "C, F are rt. 's" means "C and F are right angles". I see now.

jimthompson5910 (jim_thompson5910):

AB = DE so the hypotenuses are equal

jimthompson5910 (jim_thompson5910):

BC = EF, one pair of legs are equal

jimthompson5910 (jim_thompson5910):

so I'm sure you can guess that you use HL (hypotenuse length)

jimthompson5910 (jim_thompson5910):

to prove the triangles being congruent

OpenStudy (countrygirl1431):

so HL right?

jimthompson5910 (jim_thompson5910):

oops HL = hypotenuse LEG not length

jimthompson5910 (jim_thompson5910):

yeah HL

OpenStudy (countrygirl1431):

ok thanks this is kinda hard for me to understand im not that good at geometry
