Is this a parallelogram?

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) where opposite sides are parallel and equal in length.

Front

What are the properties of a parallelogram?

Back

1. Opposite sides are parallel and equal in length. 2. Opposite angles are equal. 3. The diagonals bisect each other.

Front

How can you determine if a quadrilateral is a parallelogram?

Back

A quadrilateral is a parallelogram if: 1. Both pairs of opposite sides are parallel. 2. Both pairs of opposite sides are congruent. 3. One pair of opposite sides is both congruent and parallel.

Front

If SV = x + 3 and VU = 2x - 1, what is the value of x if SV = VU?

Back

x = 4.

Front

If TU = 4x - 3 and SV = x + 3, what is the value of x if TU = SV?

Back

x = 5.

Front

What does it mean for the diagonals of a parallelogram to bisect each other?

Back

It means that each diagonal divides the other into two equal parts.

Front

If the angles of a parallelogram are 70 degrees and 110 degrees, what can you say about the other two angles?

Back

The other two angles are also 70 degrees and 110 degrees, as opposite angles in a parallelogram are equal.

Front

In parallelogram STUV, if SV = 5 and VU = 5, what can you conclude about ST and TU?

Back

ST and TU are also equal to 5, as opposite sides of a parallelogram are equal.

Front

What is the relationship between the consecutive angles of a parallelogram?

Back

Consecutive angles of a parallelogram are supplementary, meaning they add up to 180 degrees.

Front

If one angle of a parallelogram is 60 degrees, what are the measures of the other angles?

Back

The opposite angle is also 60 degrees, and the consecutive angles are 120 degrees each.
