Practice Triangle Congruence

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a method to prove triangle congruence where two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a method to prove triangle congruence where two angles and the included side of one triangle are congruent to the corresponding parts of another triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a method to prove triangle congruence where two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a method to prove triangle congruence where all three sides of one triangle are congruent to the corresponding sides of another triangle.

Front

What does NEI stand for in triangle congruence?

Back

NEI stands for Not Enough Information, indicating that there is insufficient data to determine triangle congruence.

Front

Which triangle congruence theorem cannot be used to prove triangles congruent?

Back

AAA (Angle-Angle-Angle) cannot be used to prove triangles congruent because it does not provide information about the size of the triangles.

Front

What additional information is required for two triangles to be congruent by ASA?

Back

One side must be included between the two angles.

Front

What is the definition of triangle congruence?

Back

Triangle congruence means that two triangles are identical in shape and size, having corresponding sides and angles that are equal.

Front

What is the significance of the HL theorem in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a method used to prove the congruence of right triangles by showing that the hypotenuse and one leg are congruent.

Front

How can you prove triangles are congruent using the SSS theorem?

Back

By showing that all three sides of one triangle are equal to the three sides of another triangle.
