Conjecture about the properties that change and the properties that stay the same when creating quadrilaterals that are not parallelograms. Check all that apply. The sum of the interior angles will still be 360°. Both pairs of opposite sides will not be parallel. Both pairs of opposite sides will not be congruent. The diagonals will not bisect each other.

A quadrilateral is a four sided shape with two diagonals that bisects each other. The sum total of the interior angles is always 360° for any quadrilateral no matter the shape of the quadrilateral.

It must be noted that both pairs of opposite sides of some quadrilaterals are equal e.g Parallelogram while some are not e.g Trapezium, rhombus, trapezoid etc.

When creating quadrilaterals that are not parallelograms, the following property of such quadrilateral will therefore remains the same.

• The sum of the interior angles will still be 360°.

The following properties will change when creating quadrilaterals that are not parallelograms.

• Both pairs of opposite sides will not be parallel. e.g Trapezoids and rhombus

• Both pairs of opposite sides will not be congruent (will not be the same)
