This activity includes 15 problems where students need to calculate the missing angle in each triangle or quadrilateral. Then students can check their answers using the QR code found on each card.
The cards are designed to guide students through the process: First identify the type of polygon, identify how many total degrees are found within the shape, and then determine the missing angle.
