So in this question, we're given two triangles.
00:04
So we have triangle acb or abc.
00:08
And then we also have triangle hgi.
00:13
And we're given some information about them, mainly that they are both right triangles where these angles are the right angles.
00:22
And then ac is 15, cb is 20, hi is 12, and then gi is 9.
00:29
And we're asked how to solve for this being a side -angle -side similarity.
00:38
So we know that they're not congruent because the sides obviously are not the same, but we can check to see if they are similar.
00:46
And the question says in order to prove that they are side -angle -side similarity, it needs to be shown that.
00:53
So i'm going to answer that question of what needs to be shown.
00:56
So in a lot of cases, math people want us to prove that right angles are congruent.
01:03
So you might need to prove that angle c is congruent to angle i.
01:09
But the bigger piece that needs to be proven is that the sides are proportional...
