Triangle Puzzles: The Star Tower
At the Star Tower, Professor Luna Moon draws triangles between the stars. Find a triangle’s missing angle, then use it to name the triangle!
Remember: The 3 angles of any triangle add up to 180°. To find a missing angle, add the two you know, then take that away from 180°. Then look at the biggest angle to name the triangle.
Magic trick: Tear the 3 corners off a paper triangle and put their points together: they make a straight line, 180°!
