Understanding Reflections in Geometry

What is a key characteristic that differentiates a reflection from a translation?

• A reflection involves enlarging the figure.

• A reflection involves rotating the figure.

• A reflection involves sliding the figure.

• A reflection involves flipping the figure.

What is the line called over which a figure is reflected?

• Axis of symmetry

• Line of reflection

• Line of symmetry

• Axis of rotation

When a figure is reflected, what remains unchanged?

• The figure's size and shape

• The figure's color

• The figure's position

• The figure's orientation

How do you determine the new position of a point after reflection over a line?

• By sliding the point along the line

• By enlarging the point

• By measuring the distance from the line and placing it on the opposite side

• By rotating the point around the line

What is the first step in reflecting a quadrilateral over the y-axis?

• Rotate the quadrilateral

• Plot the original points

• Slide the quadrilateral

• Change the color of the quadrilateral

When reflecting a triangle over the x-axis, what happens to the coordinates of a point?

• Neither coordinate changes

• Both coordinates change sign

• The y-coordinate changes sign

• The x-coordinate changes sign

What happens to the size of a figure when it is reflected?

• It becomes larger

• It becomes smaller

• It remains the same

• It changes shape

In the context of reflections, what does 'congruent' mean?

• Different size, different shape

• Same size, same shape

• Different size, same shape

• Same size, different shape

What tool is suggested to help visualize the line of reflection?

• A ruler

• A protractor

• A compass

• A highlighter

What is the result of reflecting a figure over an axis?

• A rotated figure

• A translated figure

• A congruent figure

• A distorted figure
