Exam: Skill #72- Classify Quadrilaterals

The figure provided is a rectangle because it has four sides and four right angles. A rectangle is a quadrilateral with opposite sides that are equal in length and parallel to each other. In this figure, all four sides are equal in length and the opposite sides are parallel, satisfying the properties of a rectangle.

A square is a quadrilateral that has four right angles and all sides are congruent. The presence of four right angles means that each angle of the square measures 90 degrees, making it a right angle. Additionally, all sides of a square are equal in length, which is known as being congruent. Therefore, a square fits the criteria of having four right angles and congruent sides.

The figure below is classified as a trapezoid because it has four sides, two of which are parallel. A trapezoid is a quadrilateral with one pair of parallel sides. In this figure, the top and bottom sides are parallel, while the other two sides are not. Therefore, it fits the definition of a trapezoid.

The figure shown is a rhombus because it has four equal sides and opposite angles that are congruent. A rhombus is a quadrilateral with all sides of equal length. Therefore, based on the given information, the figure can be classified as a rhombus.

Quadrilaterals have four angles because they are polygons with four sides. Additionally, the sum of the angles in a quadrilateral is always 360 degrees.
