Which of the following is not a property of a parallelogram?

• Has two pairs of opposite sides that are parallel and equal in length

• Opposite angles are equal, and adjacent angles are supplementary (sum to 180°)

• Has symmetry and 180-degree angles

• Has two diagonals that bisect each other but are not equal in length

In the figure ABCD, it can be proven that AB = DC and AD = BC. Based on the proof, determine the congruence property.

• Angle, Side, Angle

• Side, Side, Side

• Side, Angle, Side

• Angle, Angle, Angle

Determine the values of x and y in the following parallelogram ABCD.

• x = 70, y = 3

• x = 50, y = 3

• x = 60, y = 3

• x = 55, y = 3

In the figure ABCD below, find the values of x and y!

• x = 4, y = 14

• x = 5, y = 3.5

• x = 4, y = 7

• x = 4, y = 3.5

Look at the following image! The measure of angle BAC is...

• 24 cm

• 28 cm

• 55 cm

• 65 cm

In the image below, if AD//BC and BM = CM, determine the triangles that have the same area as ΔABM, except...

• Area of ΔDMC

• Area of ΔAMD

• Area of ΔAMC

• Area of ΔDBM

If we denote O as the intersection point of the two diagonals of trapezium ABCD, for BC with AD//BC, determine the triangle that has the same area as ΔAB.

If we assume O is the intersection point between the two diagonals of trapezium ABCD, for BC with AD//BC, determine the triangle that has the same area as ΔABC.

In trapezium ABCD shown, it can be proven that AB = DC and AD = BC. Based on the proof, determine the congruence property.

• Side, Side, Side

• Side, Angle, Side

• Angle, Angle, Angle

In ABCD in the following images, find the values of x and y.

• x = 70, y = 110

• x = 70, y = 100

• x = 65, y = 115

• x = 75, y = 180
