I can name congruent parts of congruent triangles.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

If ∆ABC ≅ ∆XYZ, what can we conclude about the sides AB and XY?

Back

AB ≅ XY.

Front

What is the significance of the order of letters in triangle congruence notation?

Back

The order of letters indicates the corresponding parts of the triangles. For example, in ∆ABC ≅ ∆XYZ, A corresponds to X, B to Y, and C to Z.

Front

If ∆LMK ≅ ∆LMT, what can we say about the angles ∠K and ∠T?

Back

∠K ≅ ∠T.

Front

What is the relationship between corresponding sides of congruent triangles?

Back

The corresponding sides of congruent triangles are equal in length.

Front

If ∆FGH ≅ ∆VHW, which sides are congruent?

Back

FG ≅ VH, GH ≅ HW, and FH ≅ VW.

Front

What does the symbol '≅' represent in geometry?

Back

The symbol '≅' represents congruence, indicating that two figures have the same shape and size.

Front

If two triangles are congruent, what can we say about their areas?

Back

If two triangles are congruent, their areas are equal.

Front

What is the importance of corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal, which helps in proving triangle congruence.

Front

How can you determine if two triangles are congruent using side lengths?

Back

If all three pairs of corresponding sides are equal in length, the triangles are congruent (Side-Side-Side postulate).
