The sophomores are close to finishing their chapter on right triangles.  The geometry class started the chapter learning how to simplify radicals.  We then used that skill to help us with the Pythagorean Theorem. The Pythagorean Theorem is used to find the side lengths of right triangles.  After that, we learned how to find side lengths and angle measurements with sine, cosine and tangent. I told the class it was important to learn these two skills because we use them in future chapters, but more importantly they will see them on the ACT.
