A ​ (a)   is a transformation​ that doesn't change the size or shape of a geometric figure

• nonrigid transformation

• rigid transformation

Answer explanation

A rigid transformation is a transformation that doesn't change the size or shape of a geometric figure, making it the correct choice.

Match the following

• Point

• A part of a line that is bounded by two distinct end points

• Line Segment

• A specific location, it has no dimension and is represented by a dot

• Ray

Which series of transformations were performed on the figure?

• Translation 5 units down, reflection over the y-axis

• Reflection over the x-axis, translation 6 units to the right

• Rotation 90^o clockwise, reflection over the x-axis

• Rotation 180^o clockwise, reflection over the y-axis

Answer explanation

The correct series of transformations performed on the figure are rotation 90° clockwise, followed by a reflection over the x-axis.
