Back

SSS (Side-Side-Side) Congruence Postulate.

Front

What rule can be used to prove that two triangles are congruent if two sides and the included angle are equal?

Back

SAS (Side-Angle-Side) Congruence Postulate.

Front

What rule can be used to prove that two triangles are congruent if two angles and the included side are equal?

Back

Front

What rule can be used to prove that two triangles are congruent if two angles and a non-included side are equal?

Front

What rule can be used to prove that two right triangles are congruent if the hypotenuse and one leg are equal?

Back

HL (Hypotenuse-Leg) Congruence Theorem.

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the effect of reflecting a point across the y-axis?

Back

The x-coordinate of the point changes sign, while the y-coordinate remains the same.

Front

What is the effect of rotating a point 90 degrees clockwise about the origin?

Back

The new coordinates (x, y) become (y, -x).
