2. How would you know if a quadrilateral is a parallelogram?

3. Explain why every parallelogram is a quadrilateral but not every quadrilateral is a parallelogram



​

Answer 1

1. Differentiate quadrilateral from parallelogram? The main difference between parallelogram and quadrilateral is that a parallelogram is a four-sided shape which has its opposite sides having an equal length to each other, and on the other hand, the quadrilateral is a four-sided shape that may or may not have its opposite sides equal to each other as such like the parallelogram.

2. How would you know if a quadrilateral is a parallelogram? Here are six ways to mathematically prove a given quadrilateral is a parallelogram.

3. Explain why every parallelogram is a quadrilateral but not every quadrilateral is a parallelogram

I don know

Explanation:

Answer 2

A quadrilateral is any figure with 4 sides. A parallelogram is a special type of quadrilateral in that its opposite sides are parallel to each other. Differentiating itself from a parallelogram.

If the opposite sides of a quadrilateral are congruent, then the figure is a parallelogram. Opposite Angles Theorem states: "If the opposite angles of a quadrilateral are congruent, then the figure is a parallelogram."

Credit to:cfjormetes" A parallelogram is a quadrilateral with 2 pairs of opposite, equal, and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal, and parallel sides BUT ALSO forms right angles between adjacent sides. ... This is not true for all parallelograms since isn't necessary that any of the angles is 90°."
