What is the SAS Triangle Congruence Theorem?

Back

The SAS (Side-Angle-Side) Triangle Congruence Theorem states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Front

What does it mean for two segments to be congruent?

Back

Two segments are congruent if they have the same length.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

How do you determine if two triangles are congruent using the SAS theorem?

Back

To determine if two triangles are congruent using the SAS theorem, check if two sides of one triangle are equal to two sides of another triangle and that the angle between those sides is also equal.

Front

What is the significance of the included angle in the SAS theorem?

Back

The included angle is the angle formed between the two sides being compared. It is crucial for establishing congruence in the SAS theorem.

Front

What is the relationship between parallel lines and slopes?

Back

Parallel lines have the same slope, meaning they rise and run at the same rate.

Front

What is the equation of a line in slope-intercept form?

Back

Front

What additional information is needed to prove triangle congruence by SAS?

Back

To prove triangle congruence by SAS, you need to know two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle.

Front

What is the definition of a rotation in geometry?

Back

A rotation in geometry is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

Front

How do you find the center of rotation for two congruent figures?

Back

The center of rotation can be found by identifying the point that remains fixed while the other points of the figure move in a circular path around it.
