Identify all the quadrilaterals in the list that have four equal sides

start with a square.

The others should also be easy. If not, look 'em up to be sure.

To identify the quadrilaterals in the list that have four equal sides, you need to look for shapes with congruent opposite sides. Here are some common quadrilaterals that have four equal sides:

1. Square: A square is a quadrilateral with all four sides equal in length and all angles equal to 90 degrees.

2. Rhombus: A rhombus is a quadrilateral with all four sides equal in length. The opposite angles are equal, but they are not necessarily right angles.

Note: Other types of quadrilaterals like rectangle and kite may have two pairs of equal sides, but not all four sides equal.

To identify all the quadrilaterals in a list that have four equal sides, you need to examine the properties of each quadrilateral in the list. Here is the step-by-step process to determine the quadrilaterals with four equal sides:

1. Start by reviewing the list of quadrilaterals and their properties.
2. Look for quadrilaterals that are described as having four equal sides. These will be your potential candidates.
3. Verify if the properties of the potential candidates match the properties of a quadrilateral with four equal sides.
4. The quadrilateral that meets the condition of having four equal sides is called a square. It is the only quadrilateral that satisfies this condition.

Therefore, in the given list, the only quadrilateral that has four equal sides is the square.
