A quadrilateral with 4 sides that are equal and has all 90 degree angles
a polygon with 8 sides
5 sided polygon
a flat, two-dimensional (2D) shape with straight sides that is fully closed. The sides must be straight. A shape with curved sides is not a polygon.
A parallelogram with four equal sides
A polygon with three sides and one 90 degree interior angle.
A triangle with three equal length sides and angles each 60 degrees.
A triangle with no equal sides
A quadrilateral with four right angles and opposite sides the same length

6 sided polygon
7 sided polygon
10 sided polygon
9 sided polygon
A quadrilateral with two pairs of parallel sides and diagonally opposite angles equal
Four-sided quadrilateral with one pair of parallel sides
A quadrilateral that has two pairs of sides of equal length and one pair of opposite angles.
A triangle that has 2 equal sides and angles
Two of the angles in a triangle are 70° and 40° degrees. Explain why this cannot be an equilateral triangle.
