To identify a shape that is not equilateral, we need to understand what it means for a shape to be equilateral.

A shape is considered equilateral when all of its sides are of equal length.

Now, let's look at the given options:

A) A rhombus is a four-sided polygon with opposite sides that are parallel and equal in length. It is possible for a rhombus to have sides that are not equal, so a rhombus is not necessarily equilateral.

B) A rectangle is a quadrilateral with four right angles. Although the opposite sides of a rectangle are equal in length, the adjacent sides can vary, so a rectangle is not necessarily equilateral.

C) A square is a quadrilateral with all four sides of equal length and four right angles. Therefore, a square is an example of an equilateral shape because all of its sides have the same length.

D) A regular polygon is a polygon with all sides and angles that are equal. Thus, a regular polygon is an example of an equilateral shape.

Based on this analysis, the shape that is NOT equilateral out of the given options is the rectangle (option B).

Now, let's determine the shape that is NOT equiangular.

A shape is considered equiangular when all of its angles are of equal measure.

Let's examine the options once again:

A) A rhombus is a quadrilateral with opposite sides that are parallel and equal in length. Although the angles in a rhombus are not necessarily equal, it is still possible for a rhombus to have equal angles, so a rhombus can be equiangular.

B) A rectangle is a quadrilateral with four right angles. Since a rectangle has equal angles (90 degrees), it is an example of an equiangular shape.

C) A square is a quadrilateral with four right angles, and all four angles in a square are equal (90 degrees). Thus, a square is an example of an equiangular shape.

D) A regular polygon is a polygon with all sides and angles that are equal, so it is an example of an equiangular shape.

None of the given options represent shapes that are NOT equiangular because they all have equal angles.
