Exterior Angle Theorem Digital Pixel Art | Angles of Triangles Spring Math

Easy to assign virtual or in-person, and with Google Classroom.

Great to pair with triangle sum theorem and parallel lines cut by a transversal pixel art activities! This activity is differentiated, one level contains easier problems where students solve for the missing angle in the triangle, while the second level contains more complex problems where students have to set up equations with variables to find x.
