Types of Quadrilaterals

Types of Quadrilaterals

A quadrilateral has four sides and four angles. Use what we have learned in class to classify each of the following quadrilaterals based on their sides and angles.

Trapezoids

• four sides and four angles

• ONLY one pair of parallel lines

Multiple Select

Which of the following is a trapezoid? SELECT THE TWO THAT ARE TRAPEZOIDS

Parallelograms

• four sides and four angles

• two pairs of of parallel lines

• opposite sides are equal

Multiple Select

Which of the following are NOT parallelograms? Select the TWO that are NOT parallelograms.

Multiple Select

Some parallelograms have special attributes. Which of the following shapes also fit the description of a parallelogram? SELECT ALL THAT ARE PARALLELOGRAMS

Ask yourself, "Does this shape have 2 sets of parallel sides?" to find the parallelograms.

• square

• trapezoid

• rectangle

• circle

Rectangles

• have four sides

• have four right angles

• two sets of parallel sides

Multiple Choice

Which of the following is a rectangle?

Multiple Choice

Why is this parallelogram not considered a rectangle?

• it doesn't have four sides

• it doesn't have two sets of parallel sides

• it doesn't have four right angles

Squares

• have four equal sides

• have four right angles

• two sets of parallel sides

Multiple Choice

Which of the following is a square?

Multiple Choice

Rectangles and squares are very similar, but something must be true about a square to set it apart. What is the special attribute that a square must have?

• all angles are 90 degrees

• all 4 sides must be equal in length

• two sets of parallel sides

• four sides

Rhombuses

• have 4 equal length sides

• have opposite sides that are parallel

• opposite angles are equal to one another

Multiple Select

Which of the following are rhombuses? Remember, all sides must be equal and opposite angles must be equal. SELECT THE TWO THAT ARE RHOMBUSES

Multiple Choice

We saw that a square is also a special type of rhombus. All squares are rhombuses but all rhombuses are NOT squares. Why do you think that is true?

• Rhombuses don't have to have 4 sides of equal length but squares do

• Rhombuses do not have to have right angles but square do

• Squares only have one set of parallel sides but rhombuses have two

Multiple Choice

A waiter at a restaurant used a rectangular tray to serve some cookies. Which one of the follow statements is true about the sahape of the tray?

• The tray has four acute angles.

• The tray has two obtuse angles.

• The tray has four right angles.

• The tray has two acute angles.
