help please!! :) Which additional congruence statement could you use to prove that triangle CAB is congruent to triangle CAD by HL? BD CONGRUENT AC AC CONGRUENT AC AD CONGRUENT AD AB CONGRUENT AD https://rialto5819-ehs-pps.gradpoint.com/Resource/2146263,72F,0,0,0,0,0/Assets/testitemimages/geometry_a/congruent_triangles/mc109-1.jpg

AC = AC by default (reflexive property), so you don't need this since it's practically given

jimthompson5910 (jim_thompson5910):

so choice B is out

jimthompson5910 (jim_thompson5910):

choice C is completely useless, so that's out too

jimthompson5910 (jim_thompson5910):

since AC = AC, we have a leg what is the hypotenuse?

ad

jimthompson5910 (jim_thompson5910):

so we need AB = AD to use HL

d

jimthompson5910 (jim_thompson5910):
