Parallel Lines Cut by a Transversal Digital Escape Room

Inside the case file

Lock the lesson and hand over a link. Your students step into an interactive escape room where every locked door hides an angle puzzle from parallel lines cut by a transversal. Solve it, reveal the code, and work your way out before time runs out.

It's a no-prep, self-checking review game that runs in any browser — no apps, no logins, no printing. Just send the link and let them race the clock.

Quick details

The mission

The vault is locked behind a grid of parallel lines and transversals. Find each missing angle, collect the codes, and crack the vault before the alarm sounds.

How the escape room works

• Open the private link — no app or login required.
• Work through a series of animated angle-finding challenges.
• Each correct answer reveals a code that unlocks the next room.
• Wrong answers won't open the lock, so the room checks itself.
• Crack the final code to escape and win.

What's included

• An interactive escape room hosted on a private site — animated, with randomized answers for replayability.
• No Boom Cards, Google Slides, logins, or subscriptions.
• A PDF containing your private access link to share via Google Classroom, email, or any LMS.

Skills covered

• Identifying corresponding, alternate, and co-interior angles
• Finding missing angles formed by a transversal
• Applying angle relationships to solve for unknowns
