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

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
