Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape.

Front

What are the three main types of transformations?

Back

The three main types of transformations are translations, reflections, and rotations.

Front

What is a translation?

Back

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

Front

How do you describe a translation?

Back

A translation is described by the direction and distance the shape moves, such as '2 units right' or '3 units up'.

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point, known as the center of rotation.

Front

How do you translate a point in the coordinate plane?

Back

To translate a point, you add the translation values to the x and y coordinates of the point.

Front

What does it mean to translate a shape 'left 2, up 9'?

Back

It means to move the shape 2 units to the left and 9 units up from its original position.

Front

What is the result of translating triangle ABC to triangle A'B'C' by '9 down, 4 right'?

Back

The vertices of triangle ABC are moved 9 units down and 4 units to the right to form triangle A'B'C'.

Front

What is the effect of translating a shape on its size and orientation?

Back

Translation does not change the size or orientation of a shape; it only changes its position.
