Complementary, Supplementary & Vertical Angles Digital Escape Room

Inside the case file

Recruits, your mission is hidden behind the angles. Students enter an interactive spy-school escape room where every locked door guards a complementary, supplementary, or vertical angle challenge. Solve for the missing angle, reveal the code, and break out before the clock runs down.

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

Spy school has gone into lockdown and only an angle expert can get out. Use what you know about complementary, supplementary, vertical, and adjacent angles to solve for each missing measure, collect the codes, and complete the mission.

How the escape room works

• Open the private link — no app or login required.
• Work through a series of animated angle-relationship 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 complete the mission.

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 complementary, supplementary, vertical, and adjacent angles
• Writing and solving equations to find an unknown angle measure
• Applying angle relationships formed by intersecting lines
