Topic 6 Assessment

Front

What is a reflection in geometry?

Back

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

Front

What does a rotation do to a figure?

Back

It turns the figure about a point at a specified angle and direction.

Front

Define dilation in geometry.

Back

A transformation that changes the size of a figure using a scale factor.

Front

What is a translation in geometry?

Back

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

Front

How do you perform a reflection across the y-axis?

Back

You change the sign of the x-coordinates of the points of the figure.

Front

What is the scale factor in dilation?

Back

The ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

What happens to the coordinates of a point (x, y) during a translation of 2 units to the right and 3 units up?

Back

The new coordinates will be (x+2, y+3).

Front

What is the result of rotating a figure 90 degrees clockwise?

Back

The coordinates (x, y) become (y, -x).

Front

How do you translate a triangle 2 units to the left and 5 units down?

Back

Subtract 2 from the x-coordinates and 5 from the y-coordinates of each vertex.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.
