What is a translation in graphing transformations?

Back

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

What is a rotation in graphing transformations?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a certain angle.

What is a dilation in graphing transformations?

Back

A dilation is a transformation that changes the size of a figure but keeps its shape the same, either enlarging or reducing it.

If triangle ABC is reflected over the x-axis, what happens to its coordinates?

Back

The y-coordinates of the triangle's vertices change sign, while the x-coordinates remain the same.

How do you determine the translation vector from triangle ABC to triangle A'B'C'?

Back

Subtract the coordinates of A from A', B from B', and C from C' to find the translation vector.
