Transformations Review

Front

What is a reflection in geometry?

Back

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

Front

What happens to the coordinates of a point when it is reflected over the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

Reflect the point (4, 5) over the y-axis. What is the new point?

Back

(-4, 5)

Front

What is dilation in geometry?

Back

Dilation is a transformation that enlarges or reduces a figure by a scale factor.

Front

If a point (x, y) is dilated by a scale factor of 2, what are the new coordinates?

Back

(2x, 2y)

Front

What is the difference between translation and reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips it over a line.

Front

What is the result of reflecting the point (-3, -4) over the y-axis?

Back

(3, -4)

Front

Which transformation keeps the shape and size of a figure the same?

Back

Reflection and translation both keep the shape and size the same.

Front

What is the effect of reflecting a point over the x-axis?

Back

The y-coordinate changes sign, while the x-coordinate remains the same.

Front

If point (0, 0) is reflected over any axis, what will be the new coordinates?

Back

(0, 0) - The origin remains unchanged.
