Topic: Sum of the measures of the interior angles of a polygon
... Give Back HW Collect HW Notice each of the interior angles of the polygons at right measures less than 180o. These are known as convex polygons. If the polygon has at least one angle measuring more than 180o, it is called a concave polygon. ...

FINDING EXACT TRIGONOMETRIC VALUES
... Step 1. Draw the angle. Step 2. Find the reference angle. Step 3. Set up the special right triangle. Be careful to use the correct signs. Step 4. Apply the definitions we learned from the reference angle to find the trigonometric values. ...
