Question 181611: I am trying to prove triangles similar. The bigger triangle has an angle measuring 30 degrees and the two longer sides are congruent. The smaller triangles has an angle measure of 70 degrees and he two longer sides are congruent. My question is that whether or not I can prove them similar, and if so what postulate or theorem can I use?

Question 184450: How do you find out if two triangles are similar? I know that the triangles' angles must be congruent, and their sides must be proportional. How do you determine if the sides are proportional?
Here is the problem:
Are any of these triangles similar? If so, write the appropriate similarity statement.
1st triangle-CAB CA=4; CB=4; AB=5/angles A and B are congruent.
2nd triangle-PRQ PR=8; RQ not listed; QP=10
3rd triangle-XYZ XZ=8; XY not listed; ZX=8
On triangles PRQ and XYZ, angles Z and P are congruent.

Question 186533: For right triangle, denote lengths as follows: l1 and l2 the legs, h the hypotenuse, and h1 and h2 the hypotenuse segments determined by the bisector of the right angle. For the two given measures, find the other three to the nearest tenth.
h1=4, h2=9
I know that h = 4+9 = 13. I was trying to use the Triangle Angle Bisector Theorem but I don't seem to have enough information.
