What is the ASA method in triangle congruence?

Back

The ASA (Angle-Side-Angle) method states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which means their corresponding sides and angles are equal.

Front

What is the AAS method in triangle congruence?

Back

The AAS (Angle-Angle-Side) method states that 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, then the triangles are congruent.

Front

What is the significance of midpoints in triangles?

Back

A midpoint divides a segment into two equal parts, which can be used to prove congruence or similarity in triangles.

Front

What are rigid transformations?

Back

Rigid transformations are movements of figures that preserve distance and angle measures, including translations, rotations, and reflections.

Front

What is the difference between rigid transformations and non-rigid transformations?

Back

Rigid transformations maintain the shape and size of a figure, while non-rigid transformations (like dilations) change the size of the figure.

Front

What does it mean for lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect, regardless of how far they are extended.

Front

What is the definition of an altitude in a triangle?

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

What is the HL theorem in triangle congruence?

Back

The HL (Hypotenuse-Leg) theorem states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

Front

What is the SSS method in triangle congruence?

Back

The SSS (Side-Side-Side) method states that if all three sides of one triangle are congruent to all three sides of another triangle, then the triangles are congruent.
