Consider the two triangles. Triangles A B C and H G I are shown. Angles A C B and H I G are right angles. The length of side A C is 15 and the length of side C B is 20. The length of side H I is 12 and the length of I G is 9. To prove that the triangles are similar by the SAS similarity theorem, it needs to be shown that... AngleC congruent AngleC
AngleC congruent AngleG
AC/GI = HI/BC
AC/GI = BC/HI

AC/GI = HI/BC

Step-by-step explanation:

the answer is AC/GI=BC/HI

I took the test a while back and I'm pretty good at this stuff! :P

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
