Geometry A Unit 3

Front

What is a 90° clockwise rotation?

Back

A transformation that turns a figure 90 degrees in the clockwise direction around a fixed point.

Front

What does the HL theorem stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a theorem used to prove the congruence of right triangles.

Front

What does the ASA theorem stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a theorem used to prove the congruence of triangles when two angles and the included side are known.

Front

What is translation in geometry?

Back

Translation is a transformation that slides or moves a figure from one position to another without changing its shape or orientation.

Front

Can a triangle have sides of lengths 3, 8, and 9?

Back

Yes, these lengths satisfy the triangle inequality theorem.

Front

What is the definition of rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is the SSS theorem in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem used to prove the congruence of triangles when all three sides are known.

Front

What is the AAS theorem in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem used to prove the congruence of triangles when two angles and a non-included side are known.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the triangle inequality theorem?

Back

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
