Click on the image below to access the applet and explore the different ways of showing that triangles are congruent. Write down the different ways that you find. Continue exploring until you have written down four different ways. Be sure to read the instructions on the web page before you begin.
List the different combinations that created congruent triangles.
Triangles that have exactly the same size, shape, and measure are called congruent triangles.
Quick Note: It is important to understand the following angles and sides for SAS and ASA.
For Side-Angle-Side (SAS), there must be an included angle.
For Angle-Side-Angle (ASA), there must be an included side.
