Q1W8 Wednesday: Chapter 4 Review

What is a rigid transformation?

• A transformation that preserves both the shape and size of a figure.

• A transformation that changes the size but not the shape of a figure.

• A transformation that only preserves the size of a figure.

• A transformation that only preserves the shape of a figure.

A line segment has a length of 10 units. If the line segment undergoes a translation up 5 units and left 5 units from its original position, which statement is true?

• The length of the resulting line segment will be double the length of the original line segment since translations increase the lengths of line segments.

• The length of the resulting line segment will be the same as the original line segment since translations preserve the lengths of line segments.

• The length of the resulting line segment will not be the same as the original line segment since translations do not preserve the lengths of line segments.

• The length of the resulting line segment will be half the length of the original line segment since translations decrease the lengths of line segments.

Scalene triangle MNP undergoes a 180° counterclockwise rotation to form scalene triangle QRS. Which statement about triangle QRS is true?

• Triangle QRS is congruent to triangle MNP because rotations are rigid motions that preserve angle measures and side lengths.

• Triangle QRS is congruent to triangle MNP because rotations are non-rigid motions that preserve angle measures and side lengths.

• Triangle QRS is not congruent to triangle MNP because rotations are rigid motions that preserve angle measures and side lengths.

• Triangle QRS is not congruent to triangle MNP because rotations are non-rigid motions that preserve angle measures and side lengths.
