Which property of triangle congruence ensures that if Angle A is congruent to Angle B, and Angle B is congruent to Angle C, then Angle A is congruent to Angle C?

What is the condition for two triangles to be considered congruent?

Opposite sides and opposite angles in a triangle refer to which of the following?

In triangle congruence, what does correspondence between triangles indicate?

What do included side and included angle refer to in a triangle?

Congruence means having the same shape and size, denoted by the symbol of an equal sign with a tilde on top, representing the same shape and the equal sign at the bottom representing the same size.
The idea of congruence is used in objects like toys, paper bills, coins, silverware sets, and even in mass production to recognize congruent figures with the same orientation.
Properties of triangle congruence include reflexive property (Angle A is congruent to Angle A), symmetric property (If Angle A is congruent to Angle B, then Angle B is congruent to Angle A), and transitive property (If Angle A is congruent to Angle B and Angle B is congruent to Angle C, then Angle A is congruent to Angle C).
In triangle congruence, all corresponding parts must be congruent for two triangles to be considered congruent.
The sum of the three interior angles in a triangle is always 180 degrees, according to the Triangle Sum Theorem.
Included side of a triangle refers to a side where the endpoints are the vertices of two angles, while an included angle is an angle formed by two sides of a triangle.
Opposite sides and opposite angles in a triangle refer to the side or angle that is not adjacent to a given side or angle.
Correspondence in triangles is indicated by arrowheads, showing how corresponding parts of congruent triangles align.
Understanding corresponding angles and sides is crucial in identifying and proving triangle congruence.
The video emphasizes the importance of recognizing corresponding parts to establish triangle congruence accurately.
