Angle Mazes
Put your knowledge of angles to the test to make it through the maze in these fun angle maze puzzles from Naoki Inaba!
Looking for more printable geometry puzzles for your classroom? Here’s just a few examples of other geometry puzzles I have shared!
Puzzle Instructions
Find a path through each maze by being able to recognize common angle measurements. Draw a path through the maze from S to G. Each time you pass through a numbered circle, the path must form that angle in degrees.
You may pass through each circle a maximum of 1 time. Not every circle will be used.
Puzzle Source
These angle maze puzzles are the creation of prolific Japanese puzzle creator, Naoki Inaba. He offers these puzzles (as well of hundreds of others) on his website as a free pdf download. Unfortunately for me, the puzzles are all written in Japanese.
Reformatting and Translating the Instructions
After a twitter conversation today about Naoki Inaba’s Angle Mazes, I decided to translate the rules to English and condense them into fewer pages since so many of you seemed to find that useful with the Zukei Puzzles!
The original file included 38 problems for students to solve spread over 7 pages (8 pages including instructions.) I have condensed the puzzles to fit on 5 pages.
The last two puzzles are rather large and had to be placed on the 5th page. If you are content with having only 36 problems, you could just print the first four pages front and back and use only two pages.
I used these as a quick warm-up with my trig class yesterday, and my students really seemed to enjoy them. My student aide in my trig class asked if I could print all of the puzzles for him.
I think that means this puzzle is a winner! If I taught geometry, I would definitely find a way to incorporate these into my class. I think I will start using them as warm-ups in my Algebra 1 classes.
I’m looking forward to translating and making printer friendly versions of more puzzles soon.

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!

Wow, thanks! I saw them on your Twitter last night and was intrigued. Am I assuming correctly that the x on the lines (starting in #7) means that you can't go that way?
Correct!
Sarah, do you have any of his books? Or are all of these puzzles downloaded from his website? – Wendy Menard
I don't have any of his books. I have downloaded all of his puzzles off of his website. You might have to use Google Translate to help you navigate!
I use these as entry tasks for my Geometry classes- one page per day. The kids love them. I also hide the author's name and the name of the puzzle because my resourceful and competitive students tend to google the answer keys… I will give credit to the author on the last day of our puzzling.
I love this idea! Going to be teaching Geometry for the first time in a few years starting next week – thank you for starting me off!
Great idea! I'd like to find a way to use logic puzzles as a warm-up in my Algebra classes for next year!
Do you need to keep on the grey lines or can i (for instance) go straight down from S in puzzle one page one, or even diagonally in any of the first 6? Also am I missing something or is it impossible to deal with a 180 since this would send you back to the spot you'd just come from, therefore breaking the rule about going through twice?
How do I complete this , i need help for my end of the unit test.
Hi is there a unique solution to every one of these puzzles?
I believe so!
@Sarah Carter, Thanks!
