8th math: Transformations QUEST

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to create a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

What does it mean to reflect a shape over the y-axis?

Back

To reflect a shape over the y-axis, you flip it across the y-axis, changing the sign of the x-coordinates of the points.

Front

How do you translate a shape?

Back

To translate a shape, you move it a certain distance in a specified direction without changing its size or orientation.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a central point and still look the same at certain angles.

Front

What is the angle of rotation?

Back

The angle of rotation is the number of degrees a figure is rotated around a point.

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts that are mirror images of each other.

Front

What is the image in a transformation?

Back

The image is the new figure that results from applying a transformation to the original figure.

Front

How do you find the coordinates of a point after a translation?

Back

To find the new coordinates after a translation, add the translation values to the original coordinates.

Front

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

Back

When a point is reflected over the x-axis, the y-coordinate changes sign, while the x-coordinate remains the same.
