9.
Read each clue and then decide on the most specific name possible for the polygon being described. (a)
It is a closed polygon with no parallel sides. It has no right angles. All sides and angles are congruent. It has as many diagonal as it has sides. It's diagonals form a star.
(b)
It is a closed polygon with two right angles. It has one pair of parallel sides. It has only one line of symmetry. It you cut along any one diagonal, you will create one triangle and one quadrilateral.
