Congruent Figures

Front

What are congruent figures?

Back

Figures that have the same shape and size.

Front

What does it mean when we say ∆FGH ≅ ∆VHW?

Back

It means triangle FGH is congruent to triangle VHW, indicating they have the same shape and size.

Front

How do you determine if two angles are congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the significance of the order of vertices in congruence?

Back

The order of vertices matters because it indicates the corresponding angles and sides of the figures.

Front

If ∠A ≅ ∠M, what can we conclude?

Back

Angle A and angle M have the same measure.

Front

What is the symbol for congruence?

Back

The symbol for congruence is '≅'.

Front

What does it mean if two figures are not congruent?

Back

It means the figures do not have the same shape or size.

Front

How can you prove that two triangles are congruent?

Back

You can prove triangles are congruent using criteria like SSS, SAS, ASA, AAS, or HL.

Front

What is the SSS congruence criterion?

Back

SSS stands for Side-Side-Side; it states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the SAS congruence criterion?

Back

SAS stands for Side-Angle-Side; it states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
