Question

What other information do you need to prove the triangle congruent using the SAS Postulate? It is a workpad question not multiple choice.

Answer 1

side angle side

well we need to know that there are two equal angles

(the "side" at the middle are equal for both triangles )

Answer 2

so what we really need more here
is to know that AC is perpendicular to BD.

Answer 3

because the two angles that we need to be equal are ACD and BCA

Answer 4

@Coolsector I am confused I thought with SAS we have to have 2 congruent sides (which we have) and one congruent angle . I need help figuring out which angle to use . would I use angle C is congruent to angle C or B is congruent to D?

Answer 5

this is the angle between the two sides..
so C to C.

Answer 6

are you there ?
