Polygon Polygon Triangle Quadrangle An enclosed shape with 3 or more straight sides. Polygon Triangle Quadrangle

Triangle Any 3-sided polygon Equilateral, isosceles, scalene, right-angle

Equilateral Triangle All 3 sides are equal lengths. Vertices Sides

Isosceles Triangle Vertices Sides 2 sides are equal length and the 3rd side is different. Vertices Sides

Scalene Triangle All 3 sides are different lengths. Vertices Sides

Right Angle Triangle One angle forms a right angle—90 degrees. Vertices Sides

Quadrangle Any 4-sided polygon Square, rectangle, parallelogram, rhombus, trapezoid There are 2 sets of parallels on each quadrangle except a trapezoid (only has 1 set)

Square All 4 sides are equal lengths. There are 2 sets of parallels. They have 90 degree angles. Vertices Sides

Rectangle Vertices Sides 2 short and 2 long sides of equal lengths. There are 2 sets of parallels. They have 90 degree angles. Vertices Sides

Parallelogram Vertices Sides 2 short and 2 long sides of equal lengths. There are 2 sets of parallels. They do not have a 90 degree angle. Vertices Sides

Rhombus Vertices Sides All 4 sides are equal lengths. There are 2 sets of parallels. They do not have a 90 degree angle. Vertices Sides

Trapezoid 4 sides of different lengths. There is 1 set of parallels. Vertices Sides
