Quarter 2 Review (Unit 5-first half of 7)

Front

What is the Third Angles Theorem?

Back

The Third Angles Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.

Front

What does SSS stand for in triangle congruence?

Back

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

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem that states 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.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a theorem that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem that states if two angles and a non-included side of one triangle are equal to two angles and a corresponding non-included side of another triangle, the triangles are congruent.

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a theorem that applies to right triangles, stating that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.

Front

How do you find the measure of an angle using the Third Angles Theorem?

Back

To find the measure of an angle using the Third Angles Theorem, subtract the sum of the known angles from 180 degrees.

Front

What is the formula to find the length of a side in a right triangle?

Back

Front

If two triangles have two pairs of congruent angles, what can be concluded about the triangles?

Back

If two triangles have two pairs of congruent angles, the triangles are similar, and their corresponding sides are in proportion.

Front

What is the significance of the SSA condition in triangle congruence?

Back

The SSA condition (Side-Side-Angle) does not guarantee triangle congruence; it can lead to ambiguous cases where two different triangles can be formed.
