All the solutions provided in McGraw Hill My Math Grade 3 Answer Key PDF Chapter 14 Lesson 4 Quadrilaterals will give you a clear idea of the concepts.

Some quadrilaterals have sides that are parallel, or equal distance apart. Math in My World

Example 1

The Eiffel Tower shown is in Paris, France. Describe whether any of the sides in the quadrilateral outlined in green are parallel. The top and _____________ sides of the quadrilateral are parallel.
A quadrilateral with exactly one pair of parallel sides is a trapezoid.
So, the quadrilateral outlined in green is a _____________.
Some quadrilaterals have both pairs of opposite sides parallel. Those quadrilaterals are called parallelograms. Parallelograms have the attributes shown in the table below. Parallelograms

• both pairs of opposite sides parallel
• opposite sides have the same length
• opposite angles are the same size

The top and bottom sides of the quadrilateral are parallel.
A quadrilateral with exactly one pair of parallel sides is a trapezoid.
So, the quadrilateral outlined in green is a Trapezoid.

There are many kinds of parallelograms. You can classify quadrilaterals, including parallelograms, using the following attributes.

• side lengths
• parallel sides
• right angles

Example 2

Use a centimeter ruler to measure the side lengths of each parallelogram below to the nearest centimeter. Record your results in the table. Which parallelograms have all sides equal in length? _______________
Which parallelograms have four right angles? _______________
A rectangle is a parallelogram with four right angles.
A rhombus is a parallelogram with four equal sides.
A square is a parallelogram with four right angles and four equal
Figure 1 is a _______________ .
Figure 2 is a rectangle, a rhombus, and a _______________
Figure 3 is a _______________.
Given that the parallelograms are figure 1, figure 2 and figure 3.
Know use a centimeter scale and measure the lengths of the parallelograms and not in the table. The figure 2 and figure 3 parallelograms have all sides equal in length.
The figure 1 and figure 3 parallelograms have four right angles
Figure 1 is a rectangle.
Figure 2 is a square.
Figure 3 is a rhombus.

Talk Math
