**Polygons_________________________________________****1.**: It is a polygon with three sides and three angles. The three angles always add 180º.

__Triangle__**Equilateral Triangle**: Three equal sides and three equal angles, always 60º.**Isosceles Triangle:**Two equal sides and two equal angles.**Scalene Triangle**: No equal sides and no equal angles.

**2.**Quadrilateral just means “four sides”. Therefore, any four sided shape is a quadrilateral, but the sides have to be straight, and it has to be 2 dimensional.

__Quadrilateral__.**Square:**Four equal sides. Four equal angles, always 90°.**Rectangle**: Opposite sides are parallel and of equal length. Four equal angles, always 90°.**Rhombus:**Four equal sides. Opposite angles are parallel.
