If an angle is reflected across the y-axis, how does its measure change?

Back

The measure of the reflected angle is equal to the measure of the original angle.

What is the relationship between two parallel lines after they are reflected across the x-axis and then rotated 180° about the origin?

Back

The lines remain parallel to each other.

What is the effect of a reflection on the coordinates of a point?

Back

A reflection across the y-axis changes the sign of the x-coordinate, while a reflection across the x-axis changes the sign of the y-coordinate.

Define translation in geometry.

Back

Translation is a type of transformation that moves every point of a shape the same distance in the same direction.

What is the result of rotating a shape 180° about the origin?

Back

The shape will be in the opposite position, but its size and shape will remain unchanged.

What is the significance of congruency in transformations?

Back

Congruency indicates that two shapes are identical in shape and size, even if they are in different positions.
