Solve for the missing angles (x & y). Be prepared to show how you got your answers & don't forget your unit of measure (degrees).

What do you notice about angle y?


How can you solve for the exterior angle?

Using what you've learned over the last few days, solve for angles a, b, and c. Explain the method you used to solve each angle.



Next, draw a quadrilateral in your math notebook. Extend the sides (see example below). Measure the internal angles of the quadrilateral using a protractor. Using what you know about complementary and supplementary angles, find the measurements of the exterior angles WITHOUT using a protractor.
