Quadrilaterals Is a polygon that has four sides and all angles add up to 360 o

Square

2 pair of parallel sides

Square 4 right angles

Square All sides equal in length (congruent)

Square ShapeParallelAnglesSides Square2 pair of parallel sides 4 right anglesAll sides equal in length

Scalene Triangle

No Parallel Sides Any Angles (must add up to 180)

Scalene Triangle All Sides of Scalene Triangle are Different

Scalene Triangle ShapeParallelAnglesSides Square2 pair of parallel sides 4 right anglesAll sides equal in length Scalene TriangleNo parallel sidesAny angleAll sides are different

Trapezoid

One Pair of Parallel Sides

Trapezoid Any Angles, but must add up to 360 (why?) Non-parallel sides can be equal in length Isosceles Triangles

Trapezoid ShapeParallelAnglesSides Square2 pair of parallel sides 4 right anglesAll sides equal in length Trapezoid1 pair of parallel lines Any angles-All sides different - Non-parallel can be equal (Isosceles Trapezoid ) Scalene TriangleNo parallel sidesAny angleAll sides are different
