Quadrilateral Basics

100

What is a quadrilateral?

(A shape with 4 sides)

200

True or False: A square is always a rectangle.

True

300

How many sides does a quadrilateral have?

(4 sides)

400

Name a quadrilateral with only one pair of parallel sides.

(trapezoid)

500

What do we call a quadrilateral where all sides are equal, and the angles are 90 degrees?

(Square)

Classifying Shapes

100

What shape has 2 pairs of parallel sides and no right angles?

(Parallelogram)

200

Which quadrilateral has 4 equal sides but does not always have right angles?

(Rhombus)

300

Which shape has opposite sides that are equal and 4 right angles?

(Rectangle)

400

True or False: All rhombuses are squares.

False

500

What is the difference between a rectangle and a parallelogram?

(A rectangle has 4 right angles; a parallelogram does not need to.)

Rotational Symmetry

100

What is a line of symmetry?

(A line that divides a shape into two identical parts.)

200
