Explain why the leg-leg (ll) theorem is the same as the side-angle-side (sas) postulate.

SAS postulate of congruence refers to the congruence between two pairs of corresponding sides and the congruence between one pair of corresponding angles which are formed by the two sides.

Notice that to use this postulate we just need three congruent elements of those triangles.

Similarly we have the Leg-Leg theorem which is used to demonstrate congruence between right triangles. Using this theorem would give the same result than using SAS postulate, because Leg-Leg theorem is actually based on that.

In other words, we can use LL theorem for congruence because all right triangles has a congruent angle, the right angle. So, basically, when you use the LL theorem, you are actually use the SAS postulate indirectly.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
