Presentation transcript:

6-3 Tests for Parallelograms Conditions for Parallelograms Opposite sides must be congruent Opposite angles must be congruent Diagonals have to bisect each other Opposite sides also have to be parallel

Identifying Parallelograms Ex 1: Determine if the quadrilateral is a parallelogram Ex 2: Determine if the quadrilateral is a parallalogram

Using Algebra to find values Ex 3: Solve for x and y so it’s a parallelogram Ex 4: Solve for x and y so it’s a parallelogram

Using Slope to Determine Parallelograms Ex 5: A(0, 0), B(1, 3), C(5, 3), D(4, 0)
