The video tutorial covers the steps to prove triangle congruence using various methods such as side-side-side, side-angle-side, and angle-side-angle. It includes three example problems demonstrating the use of given information, marking congruent parts, and selecting appropriate theorems. The tutorial emphasizes the importance of marking diagrams and writing statements with reasons in a two-column proof format.

What is the first step in proving triangles are congruent?

• Fill in the reasons

• Choose a method

• List the congruent parts

• Mark the given
