Essential Question
How can you classify and compare quadrilaterals? Unlock the Problem
A seating chart for a baseball field has many four-sided figures or quadrilaterals. What types of quadrilaterals can you find in the seating chart?

There are five special types of quadrilaterals. You can classify quadrilaterals by their properties, such as parallel sides and perpendicular sides. Parallel lines are lines that are always the same distance apart. Perpendicular lines are lines that intersect to form four right angles. Complete the sentence that describes each type of quadrilateral.

A general quadrilateral has 4 sides and 4 angles. A rectangle is a special parallelogram with 4 right angles and 4 pairs of congruent sides. A square is a special parallelogram with 4 congruent sides and 4 right angles. A parallelogram has opposite sides that are congruent and parallel. A rhombus is a special parallelogram with 2 pairs of congruent sides. A trapezoid is a quadrilateral with exactly 1 pair of congruent sides. So,
The types of quadrilaterals you can find in the seating chart of the field are: General Quadrilateral and Rectangle

Can the parallel sides of a trapezoid be the same length? Explain your answer.
We know that,
In a trapezoid, there is only 1 pair of parallel sides i.e., the sides that have the base angles
In an isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram).
