Chapter 3 Review

Front

What type of symmetry is shown here?

Back

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

Front

In T(x, y), what does y tell you to move?

Back

In the transformation T(x, y), y indicates movement up or down on the coordinate plane.

Front

Complete the following Reflection: Rx-axis Δ ABC= Δ A′B′C′. A= (3, 2), B= (7,-3), C= (3, 0). What are the coordinates of A′, B′, and C′?

Back

A′ (3, -2), B′ (7, 3), C′ (3, 0). This reflects the points across the x-axis.

Front

What transformation is taking place between ΔSRT and ΔMNP?

Back

Reflection is a transformation where a figure is flipped over a line, creating a mirror image.

Front

Translation means you ________ a figure.

Back

Translation means you slide a figure from one position to another without changing its shape or orientation.

Front

Define reflection in geometry.

Back

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

Front

What is rotational symmetry?

Back

Rotational symmetry exists when a figure can be rotated around a central point and still appear the same at certain angles.

Front

What does a translation transformation do to a figure?

Back

A translation transformation moves a figure in a straight line in a specific direction without altering its shape or size.

Front

How do you find the image of a point after a reflection over the x-axis?

Back

To find the image of a point (x, y) after reflection over the x-axis, the new coordinates will be (x, -y).

Front

What is the difference between reflection and rotation?

Back

Reflection flips a figure over a line, while rotation turns a figure around a point.
