To use the HL Theorem to prove two triangles are congruent, the triangles must be right triangles. Which other conditions must a
lso be met?. . A.The triangles have congruent hypotenuses and two pairs of congruent legs. . B. The triangles have congruent hypotenuses and one pair of congruent legs. . C.The triangles have two pairs of congruent legs. . D. The triangles have congruent hypotenuses . .
Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.
