Back

Reflection across the x-axis

Front

Which sequence of transformations shows that ΔABC≅ΔDEF: Reflect △ABC across the x-axis, then translate it right 1, Reflect △ABC across the y-axis, then translate it right 1, Reflect △ABC across the x-axis, then translate it left 1, Reflect △ABC across the y-axis, then translate it left 1?

Back

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

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

Front

What is a translation?

Back

A translation is a transformation that slides a figure from one position to another without turning it.

Front

What does it mean for two shapes to be congruent?

Back

Two shapes are congruent if they have the same size and shape, and can be made to coincide by transformations.
