Triangle Congruence Theorems and Conditions

The video tutorial introduces triangle congruence, explaining various congruence theorems such as side-side-side, side-angle-side, hypotenuse-leg, angle-side-angle, and angle-angle-side. Through multiple examples, the teacher demonstrates how to determine if triangles are congruent and how to create congruent triangles by adding necessary parts.

What is the primary condition for two triangles to be congruent using the Side-Side-Side (SSS) theorem?

• Two angles and the included side are equal.

• Two sides and the included angle are equal.

• All three angles are equal.

• All three sides are equal.

Why can't the Side-Side-Angle (SSA) condition be used to prove triangle congruence?

• It does not guarantee congruence.

• It requires all angles to be equal.

• It only applies to right triangles.

• It requires all sides to be equal.
