Background Tutorials

Apply the definition of similarity in terms of a dilation to identify similar figures and their proportional sides and the congruent corresponding angles

Looking at two figures that are the same shape and have the same angle measurements? You have similar figures! Learn all about it in this tutorial!

Prove two triangles are congruent by applying the side-angle-side, angle-side-angle, side-side-side, angle-angle-side, and hypotenuse-leg congruence conditions

Looking for some terminology used with right triangles? Then this tutorial was made for you! In this tutorial, you'll be introduced to the names for the different parts of a right triangle. Check it out!

Verify theorems about the relationships in triangles, including proof of the pythagorean theorem, the sum of interior angles, base angles of isosceles triangles, midsegments, and medians, and apply these relationships to solve problems

Angles are a fundamental building block for creating all sorts of shapes! In this tutorial, learn about how an angle is formed, how to name an angle, and how an angle is measured. Take a look!
