Identifying Parallel Lines in Shapes

Name the quadrilateral that has two sets of parallel lines.

• Trapezoid

• Triangle

• Parallelogram

• Rhombus

Which attribute do both A and D have that B and C do not?

• 4 sides

• at least 1 right angle

• 2 pairs of parallel lines

• at least 1 pair of parallel lines

Joe sorted shapes into two groups as shown in the picture. Which rule did he use to place shapes into Group 1?

• polygons with at least 1 right angle

• polygons with 5 sides

• polygons with equal sides

• polygons with at least 1 pair of parallel sides

Bob says that the red shape is a trapezoid. Mary says that these are both trapezoids. Who is correct?

• Mary, because both are quadrilaterals and have one pair of parallel lines.

• Bob, because only the first shape has slanted lines and looks like a trapezoid.
