TRIANGLE SIMILARITY CRITERIA
First a quick reminder of the similarity criteria for triangles, with these examples:
And now it´s time for some practice:
1. A first test.
2. In this test we will use the Basic Proportionality Theorem, also called the Thales Theorem.
3. A third test.
4. Last 18-question test.

April 10th
We are studying now COMBINATORICS. We´ve already learned all the basic concepts and formulas, but you can watch this video to remember a couple of things:
And now it´s time for some exercises and tests:
1. About permutations, try problems 1 to 6 on this page (and yes!, I know there are 2 different number 5s).
2. About combinations, try problems 1 to 5 here.
3. A first test, very easy (skip the last question).
