Transformations Practice

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run between two points on the line.

Front

What type of transformation is a translation?

Back

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

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips or mirrors an object across a line, creating a mirror image.

Front

What does a rotation do to a figure?

Back

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

Front

What is the difference between a translation and a reflection?

Back

A translation slides a figure without changing its orientation, while a reflection flips it over a line.

Front

How do you identify a reflection across the x-axis?

Back

A reflection across the x-axis changes the sign of the y-coordinates of the points of the figure.

Front

What is the result of a 180-degree rotation?

Back

A 180-degree rotation turns a figure around a point, resulting in a figure that is upside down.

Front

What is the formula for calculating slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a figure in some way, including translations, rotations, reflections, and dilations.

Front

What happens during a translation of a figure?

Back

During a translation, every point of the figure moves the same distance in the same direction.
