Which pair of congruent angles are enough to prove two triangles are congruent by ASA (Angle-Side-Angle) criterion?

Two angles and the side opposite one of them

Explanation

Two angles and one side are sufficient to establish congruence.

In triangle congruence, if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, which criterion is being used?

Side-Angle-Side (SAS)

Explanation

Matching two sides and the included angle establishes congruence.

In triangle congruence, if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, which criterion is being used?

Angle-Side-Angle (ASA)

Explanation

Matching two angles and the included side establishes congruence.

What is the name of the theorem used to prove triangles congruent if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle?

Corresponding Parts of Congruent Triangles are Congruent (CPCTC)

Explanation

Congruence of corresponding parts is maintained.

Which congruence criterion can be used to prove two triangles congruent if the lengths of two sides and the included angle of one triangle are equal to the lengths of two sides and the included angle of the other triangle?

Side-Angle-Side (SAS)

Explanation

Matching two sides and the included angle establishes congruence.

Which of the following statements about the HL (Hypotenuse-Leg) congruence criterion is true?

It requires the hypotenuse and one leg of one triangle to be congruent to the corresponding parts of another triangle.

Explanation

Congruence is based on the hypotenuse and one leg.

If two triangles are congruent, what can be said about their corresponding angles and sides?

Both their corresponding angles and sides are congruent.

Explanation

Congruence applies to both angles and sides.

In triangle congruence, which pair of triangles must have their corresponding sides and angles in the same order to be congruent?

Any type of triangles

Explanation

Order of corresponding sides and angles is not crucial for congruence.

Which of the following is NOT a valid congruence criterion for triangles?

Side-Side-Angle (SSA)

Explanation

SSA is not sufficient to ensure congruence.

#10

If two triangles are congruent, what can be said about their corresponding medians, altitudes, and angle bisectors?

Their corresponding medians, altitudes, and angle bisectors are congruent.

Explanation

Congruence extends to medians, altitudes, and angle bisectors.

#11

If two triangles are congruent, what can be said about their corresponding altitudes?

Their corresponding altitudes are congruent.

Explanation

Congruence applies to altitudes as well.

#12

Which of the following is a postulate used to prove congruence between two triangles?

Side-Angle-Side (SAS) Postulate

Explanation

SAS postulate ensures congruence.
