Question

wich of the following is not a right triangle congruency?
hl, ll, la, aa

Answer 1

I couldn't figure out the given data.

Answer 2

i dont get it either

Answer 3

h probably stands for hypotenuse
l for leg
a for angle (other than the 90 degree right angle)

Does this help?

Answer 4

i understand what your saying i just dont get all of the other acronyms

Answer 5

Congruent triangles:
SSS (3 sides of triangle A equal to 3 sides of triangle B)
SAS ( side-angle-side)
ASA (angle side angle)
so for example,
give h and l of a right triangle, we can find the other side (Pythagoras) so h,l is equivalent to SSS. Hence congruent
one of the combinations does not define congruence

Answer 6

ll gives you SAS and la gives you ASA. aa gives you AAA, which is not enough for congruence (proves similarity, tho).

Answer 7

thanks guys, i figured it out with the information you gave me
