Students find the missing side of each figure, then use their answers to eliminate suspects and unmask the villain. Perfect for geometry review, math centers, early finishers, sub plans, test prep and homework, and completely no prep - just print and go.\u003c\/p\u003e\n\n\u003cp\u003eEvery figure is drawn and fully labeled, so no measuring is needed.

Every answer matches one suspect's ID badge, so each triangle a student works out crosses another name off the list. The badge left unmatched at the end belongs to the villain, which makes the page self-checking: if two suspects are still standing, something needs another look. Real skill practice, critical thinking, and a detective hook that keeps the whole class working.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Use This Resource\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eGeometry review before state testing\u003c\/li\u003e\n  \u003cli\u003eMath centers and small groups\u003c\/li\u003e\n  \u003cli\u003eMorning work and bell ringers\u003c\/li\u003e\n  \u003cli\u003eEarly finishers and enrichment\u003c\/li\u003e\n  \u003cli\u003eSubstitute teacher plans\u003c\/li\u003e\n  \u003cli\u003eHomework and spiral review\u003c\/li\u003e\n  \u003cli\u003eEnd-of-unit right triangle practice\u003c\/li\u003e\n  \u003cli\u003eBack to school and end of year review\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDesigned for 8th grade geometry and measurement.
