Parallelograms Geometry

What does it mean if diagonals are perpendicular (⊥)?

• They bisect the vertex

• Where they intersect is a 90˚ angle

• They are equal

• They never intersect

Find the diagonals of the parallelogram QRST

• (-1,-1)

• (0,1)

• (2,2)

• (1,1)

The quadrilateral is a parallelogram.

Find the value of x

This quadrilateral is a parallelogram.

Find the value of x

AE+ED=16

• TRUE

• FALSE

Find the values of the variables for which makes up a parallelogram.

• x= 2 , y= 0

• y = 1 , x= -1
