Review the classification of quadrilaterals.

Rectangle

Practice makes perfect

Let's review the classification of quadrilaterals.

Name and Definition	Properties
Parallelogram Both pairs of opposite sides are parallel.	Opposite sides are congruent. Consecutive angles are supplementary. Opposite angles are congruent. Diagonals bisect each other.
Rhombus Parallelogram with four congruent sides.	Diagonals are perpendicular. Each diagonal bisects a pair of opposite angles.
Rectangle Parallelogram with four right angles.	Diagonals are congruent.
Isosceles trapezoid Trapezoid with legs that are congruent.	Diagonals are congruent.
Kite Quadrilateral with two pairs of consecutive sides congruent and no opposite sides congruent.	Diagonals are perpendicular.

Now let's take a look at the given figure.

In the given quadrilateral, all four angles are right. Therefore, the most specific classification of the figure is a rectangle.
