Which letters have a pair of parallel lines?

• A

• M

• K

Z - =

Multiple Select

How can we classify this shape? Select all that apply.

• Quadrilateral

• Trapezoid

• Parallelogram

• Square

• Rectangle

It has..

• 4 sides, so it's a quadrilateral!

• 2 pairs of parallel sides, so also parallelogram!

• 4 right angles, rectangle!

• It does NOT have 4 congruent sides, so it is not a square or a rhombus!

• It does NOT have exactly 1 pair of parallel sides (it has 2), so it is not a trapezoid.

Multiple Choice

Which of these can this shape NOT be classified as?

• Square

• Rhombus

• Rectangle

• Trapezoid

Since this is a square it can be classified also as...

• a quadrilateral (4 sides)

• a parallelogram (2 pairs of parallel sides)

• a rectangle (a parallelogram with 4 right angles)

• a rhombus (a parallelogram with 4 congruent sides)
