How to Write a Proof Using SSS Congruence Theorem - Congruent Triangles

The video tutorial explains how to prove triangle congruence using the two-column proof method. It begins with a problem statement involving triangles QRST, where certain sides are given as congruent. The instructor guides students through writing statements and reasons, emphasizing the importance of understanding given information. Various methods for proving congruence, such as side-side-side and side-angle-side, are discussed. The video also covers the analysis of angles and sides, highlighting the reflexive property to conclude that triangles QRT and SRT are congruent.

Why is it important to confirm that angles are equal when proving triangle congruence?

What property allows us to say that QR is congruent to QR?

What conclusion can we draw about triangle QRT and triangle SRT based on the sides we have proven to be congruent?
