Parallel and Perpendicular Lines in Capital Letters
Written by Adi Ackerman, Head Teacher
"Parallel and Perpendicular Lines in Capital Letters" is written for 4th Grade (Ages 9-10), and it covers Common Core 4.G.A.1. If your little one is a year younger but already steady on geometry, the page still works. You may just need to read the instructions out loud. And if they are older and parallel and perpendicular lines never quite stuck, this is a short review rather than busywork.
4th grade math worksheet: sort capital letters by whether their segments are parallel only, perpendicular only, both or neither. Answer key included. Part of our parallel and perpendicular lines geometry collection. Aligned to Common Core standards.
How do I use this worksheet?
Give your child an index card to test corners for right angles. Look for parallel and perpendicular lines around the house, like window frames and floor tiles. Check with the answer key.
What students will practice
- Students will tell parallel, perpendicular and intersecting lines apart.
- Students will find parallel and perpendicular sides in shapes and capital letters.
- Students will draw lines parallel or perpendicular to a given line.

How do I use this parallel and perpendicular lines worksheet?
⌄
Give your child an index card to test corners for right angles. Look for parallel and perpendicular lines around the house, like window frames and floor tiles. Check with the answer key.
What does this worksheet teach?
⌄
Sort capital letters by whether their segments are parallel only, perpendicular only, both or neither. Parallel segments never meet. Perpendicular segments meet at a right angle, a square corner. The directions on the page read: Read the Example. Then, look at the segments in each letter. Then, write each letter in the column where it belongs. An answer key is included.
Can I use this parallel and perpendicular lines worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 4th Grade geometry, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with parallel and perpendicular lines. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
What is the difference between parallel and perpendicular lines?
⌄
Parallel lines stay the same distance apart and never meet, like the rails of a train track. Perpendicular lines cross to make a right angle, a square corner, like the corner of a page. Lines that cross at any other angle are just intersecting.
How can my child check for a right angle?
⌄
Use the corner of a sheet of paper or an index card. If the corner fits exactly in the angle, the lines are perpendicular. Several sheets tell students to do this, and one has them mark each right angle with a small square.
Why use capital letters and a town map?
⌄
They show parallel and perpendicular lines in things children see every day. In H the two tall segments are parallel, and in T they are perpendicular. On the map, students find streets that run side by side and streets that cross at square corners.
Is there an answer key for each worksheet?
⌄
Yes. All six parallel and perpendicular lines sheets have an answer key.
How many 4th Grade parallel and perpendicular lines worksheets are there?
⌄
6 printable worksheets, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.
What age are parallel and perpendicular lines worksheets for?
⌄
These are written for 4th Grade students, roughly ages 9-10. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.
Are these parallel and perpendicular lines worksheets aligned to Common Core?
⌄
Yes. Each one shows the Common Core code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.
