Worksheet: Lines and Angles of 2D Shapes

In this worksheet, we will practice describing polygons by considering whether they have acute, obtuse, or right angles and the number of pairs of parallel or perpendicular sides they have.


The given quadrilateral contains two angles.

  • Aacute
  • Bright
  • Cobtuse


Look at this rectangle and answer the questions.

True or False: It contains two pairs of parallel lines.

  • ATrue
  • BFalse

True or False: It contains one pair of perpendicular lines.

  • AFalse
  • BTrue


Take a look at this shape then answer the questions.

How many angles does it have?

How many obtuse angles does it have?


Which of the following shapes has 4 sides, 2 acute angles, 2 obtuse angles, and one pair of parallel lines?

  • A
