What postulate or theorum justifies the statement..Triangle ABE is similar to Triangle CDE.

Find the values of x and y. Please explain how to find x and y!!! Soo confused. Need help! Thanks!

No, I will not do that. I do not believe in supplying fully worked out solutions. I think that we should help others learn mathematics and simply giving out a complete solution does not accomplish that objective. As you know there are others here will do that. So just wait they will come along and work it out.

i like the idea of interior angles and verticle angles

interior angles - and two parralel lines, their opposite, interior angles, along a transversal of the two parrel lines are equal

verticle angles - whenever theres an X the two opposite angles are equal

so AAA makes them similar

ok, just wanted to know. because i have a TA that uses commas for decimals as well, so i was wondering if it's a regional thing. but i guess it avoids confusion, since dots and decimals get confused sometimes.

why don't people use the x anymore to represent multiply when they get to higher mathematics? is there a problem with x?
