WEEK 18: Rigid Transformations(Describe)-DAY 1 -HU

Front

What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, meaning the figure's dimensions and angles remain unchanged.

Front

What are the three types of rigid transformations?

Back

The three types of rigid transformations are translation, rotation, and reflection.

Front

Define translation in the context of rigid transformations.

Back

Translation is a rigid transformation that slides a figure in a straight line from one position to another without changing its shape or orientation.

Front

What is rotation in rigid transformations?

Back

Rotation is a rigid transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

Front

Explain reflection in rigid transformations.

Back

Reflection is a rigid transformation that flips a figure over a line, creating a mirror image of the original figure.

Front

How do you reflect a point over the y-axis?

Back

To reflect a point (x, y) over the y-axis, change the sign of the x-coordinate, resulting in the point (-x, y).

Front

What is the result of rotating a point (3, 4) 90 degrees clockwise around the origin?

Back

The result of rotating the point (3, 4) 90 degrees clockwise around the origin is (4, -3).

Front

Describe the sequence of transformations: Reflect across the x-axis and then translate up.

Back

First, reflect the figure over the x-axis, then move the reflected figure upwards by a specified distance.

Front

What is the effect of a 180-degree rotation about the origin on the point (2, 3)?

Back

A 180-degree rotation about the origin transforms the point (2, 3) to (-2, -3).

Front

How do you perform a translation of 5 units left on the point (1, 2)?

Back

To translate the point (1, 2) 5 units left, subtract 5 from the x-coordinate, resulting in the point (-4, 2).
