Q4W4 Day 1 Transformation and Congruence Practice

Front

What is a reflection in geometry?

Back

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

Front

What does it mean for two triangles to be congruent?

Back

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

Front

What is the definition of translation in geometry?

Back

A transformation that moves every point of a figure the same distance in a specified direction.

Front

What is the transformation that occurs when a figure is rotated 180° about the origin?

Back

Each point of the figure moves to a position directly opposite its original position, effectively flipping it upside down.

Front

What does ASA stand for in triangle congruence?

Back

Angle-Side-Angle; a method to prove triangles congruent by showing two angles and the included side are equal.

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side; a method to prove triangles congruent by showing all three sides are equal.

Front

What does SAS stand for in triangle congruence?

Back

Side-Angle-Side; a method to prove triangles congruent by showing two sides and the included angle are equal.

Front

What is the significance of SSA in triangle congruence?

Back

SSA (Side-Side-Angle) cannot be used to prove triangles congruent because it can lead to ambiguous cases.

Front

What is a reflection across the x-axis?

Back

A transformation where each point (x, y) of a figure is mapped to (x, -y).

Front

What is a reflection across the y-axis?

Back

A transformation where each point (x, y) of a figure is mapped to (-x, y).
