What's the missing angle activity:
Step 1: Each group construct their own triangle and quadrilateral using a protractor and ruler.
Step 2: cut it out and tear off one angle and label the remaining angles.
Step 3: Each group will leave their shapes at their table and move to another table. Groups rotate and find everyone else’s missing angle measures.
Record your results in the table provided. (Sample on next slide)
