Look at the letters below. Circle the letter that has both parallel and perpendicular lines.

To understand this question, we need to know what parallel and perpendicular lines are. Parallel lines are lines which are an equal distance apart. No matter how much further we drew these lines, they would always be the same distance apart. Perpendicular lines are lines that meet at a right angle. Let’s look more closely at the letters now to see if we can identify which one has both parallel and perpendicular lines.

Letter A has neither. Letter C is one curved line. No parallel or perpendicular lines here. The letter E has parallel lines. It also has perpendicular lines. And the question asks us to circle the letter that has both parallel and perpendicular lines. So we need to circle the letter E. We don’t need to spend any time looking at the letters L and Z because the question asks for “the” letter. We know we’re only looking for one letter; and it’s letter E.
