Measuring Angles with a Protractor for Kids: Zero Line, Inner or Outer Row with Hash Brown the Owl

Hash Brown shows how to measure angles with a protractor: sharp or wide first (a book's square corner), the centre cross on the corner, the zero line (not the bottom edge!) along one arm, then count up from the 0 on that arm, inner row or outer row. Plus tilted angles (turn the protractor), arms too short (draw them longer) and why longer arms don't make a bigger angle. 45°, 50° and 115° worked through.
