2025 Transformations

Front

What is a scale factor in transformations?

Back

A scale factor is a number that scales, or multiplies, a quantity. In transformations, it determines how much a figure is enlarged or reduced.

Front

What does it mean for figures to be congruent?

Back

Congruent figures are figures that have the same size and shape.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that produces a figure similar to the original by enlarging or reducing it using a scale factor.

Front

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

Back

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

Front

Reflect the point (6, -3) over the x-axis. What is the new coordinate?

Back

(6, 3)

Front

What is the rule for translating a point 2 units to the right and 1 unit down?

Back

(x + 2, y - 1)

Front

What is the effect of a transformation on the area of a figure when the scale factor is greater than 1?

Back

The area of the figure increases by the square of the scale factor.

Front

If a figure is dilated by a scale factor of 1, what happens to the figure?

Back

The figure remains unchanged.

Front

What is the difference between a translation and a reflection?

Back

A translation moves a figure from one location to another without changing its shape or orientation, while a reflection flips a figure over a line.

Front

What is the result of reflecting the point (-4, 5) over the y-axis?

Back

(4, 5)
