What do you think happened to the lengths of the segments and the measures of the angles of the triangle after being reflected over the y-axis?

Multiple Select

Choose all the properties of a reflection.

• A line maps to a line. A ray maps to a ray. A segment maps to a segment. An angle maps to an angle.

• The size and shape of the figure become different.

• It preserves the measures of the segments.

• It preserves the measures of the angles.

Multiple Choice

The following are properties of reflection EXCEPT FOR:

• A reflection maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle.

• A reflection preserves lengths of segments.

• A reflection preserves degrees of angles.

• A reflection preserves the orientation of the object.

Multiple Select

Select the properties of a reflection. Choose all that apply.
