Exploring Properties of Parallelograms

The video tutorial covers the properties of parallelograms, including parallel sides, congruent sides, congruent angles, supplementary consecutive angles, and bisecting diagonals. It explains how to use these properties to solve for missing values and prove that a quadrilateral is a parallelogram.

What defines a parallelogram in terms of its sides?

• Two pairs of congruent sides

• Two pairs of parallel sides

• Four right angles

• Four sides of equal length

Which statement is true about the angles in a parallelogram?

• Opposite angles are congruent

• All angles are right angles

• All angles are obtuse

• All angles are acute

What is the result of adding two consecutive angles in a parallelogram?

• 180 degrees

• 270 degrees

• 360 degrees

• 90 degrees

What happens to the diagonals in a parallelogram?

• They are congruent

• They are perpendicular

• They bisect each other

• They intersect at a right angle

What must be true for both diagonals in a parallelogram?

• They must be perpendicular

• They must bisect each other

• They must intersect outside the shape

• They must be equal in length

If one diagonal is divided into segments of 14 and 20.7, what is the length of the other segment?

• 28

• 14

• 20.7

• 34.7

In a parallelogram, if one angle is 68 degrees, what is the measure of its consecutive angle?

• 68 degrees

• 22 degrees

• 112 degrees

• 180 degrees

If a side of a parallelogram labeled as 2x is equal to 20, what is the value of x?

• 20

• 5

• 10

• 40

How do you prove a quadrilateral is a parallelogram using angles?

• Show that all angles are equal

• Prove all angles add up to 360 degrees

• Prove opposite angles are congruent

• Show all angles are 90 degrees

Which property is used to solve for y when given the equation 4x - 3 = y/5 in the context of parallelogram properties?

• Diagonals bisect each other

• Opposite angles are congruent

• Consecutive angles are supplementary

• Opposite sides are congruent
