Orientation & Congruence

Front

What is orientation in geometry?

Back

Orientation refers to the direction in which a shape or object is positioned. It can be preserved or changed during transformations.

Front

What is congruence in geometry?

Back

Congruence means that two shapes are identical in shape and size, allowing for rotations, reflections, and translations.

Front

What transformation does NOT preserve congruence?

Back

Dilation does not preserve congruence because it changes the size of the shape.

Front

True or False: An object and its image maintain congruence if they are similar.

Back

False. Similar shapes have the same shape but not necessarily the same size.

Front

True or False: An object and its image maintain orientation after dilation.

Back

True. Dilation maintains the orientation of the shape.

Front

True or False: An object and its image maintain orientation after reflection.

Back

False. Reflection changes the orientation of the shape.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a shape from one position to another without changing its size, shape, or orientation.
