Determine which figure represents a reflection of the triangle ABC

The image of a figure by a reflection is its mirror image in the axis of reflection. So the following figure is the reflection of ABC.

-

Determine which figure represents a rotation of the triangle ABC

A rotation is turning an object across a point without changing its size or shape. So the following figure is the rotation of ABC.

-

Determine which figure represents a translation of the triangle ABC

A translation is moving an object without changing its size, shape or orientation. So the the following figure is a translation of ABC.

-

Determine which figure represents a dilation of the triangle ABC

A dilation is expanding or contracting an object without changing its shape or orientation

So the following figure represents a dilation of ABC:

-

Determine which figure represents a dilation of the triangle ABC

A dilation is expanding or contracting an object without changing its shape or orientation

So the following figure represents a dilation of ABC:

-

Determine which figure represents a reflection of the triangle ABC

A reflection is flipping an object across a line without changing its size or shape. Here we can see that the in following graph, the triangle has flipped across a vertical line.
