Exercise 27 Page 550

Recall the classification of quadrilaterals.

Graph:

Name: Parallelogram

Practice makes perfect
Let's plot the given points on a coordinate plane and graph the quadrilateral.

To determine the most precise name for our quadrilateral, let's review the classification of quadrilaterals.

Quadrilateral Definition
Parallelogram Both pairs of opposite sides are parallel
Rhombus Parallelogram with four congruent sides
Rectangle Parallelogram with four right angles
Square Parallelogram with four congruent sides and four right angles
Trapezoid Quadrilateral with exactly one pair of parallel sides
Isosceles Trapezoid Trapezoid with legs that are congruent
Kite Quadrilateral with two pairs of consecutive sides congruent and no opposite sides congruent

We can see that the quadrilateral has two pairs of parallel sides. We also know that the figure does not have any right angle. We can tell that the quadrilateral is a parallelogram.
