What is the SAS postulate anyway?

anonymous · Answer

It stands for side-angle-side. If two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

mertsj · Answer

So do the given values of x and y make the sides congruent?

anonymous · Answer

I don't know. That's why i need help on this one.

mertsj · Answer

If y = 9, what is 2y-3?

anonymous · Answer

15.

mertsj · Answer

So is that side congruent to a side of the other triangle?

anonymous · Answer

I think so.

mertsj · Answer

yes.  Because now we see that each triangle has a side whose measure is 15.
If x = 12, what is 0.5x+6 ?
