Scholarship Geometry 6-1 Worksheet #1 Name ____________________________________ Tell whether each figure is a polygon. If it is a polygon, name it by the number of its sides. 1. 2. 3. Tell whether each polygon is regular or irregular. Tell whether it is concave or convex. 4. 5. 6. 7. Find the measure of each interior angle of quadrilateral RSTV. Find the value of x in each figure. You do NOT need to find all the angle measures. 8. 9. 10. 11. The interior angles of a convex pentagon are consecutive multiples of 4. Find the measure of each interior angle. 12. Polygon PQRST is a regular pentagon. Find the values of x, y, and z.
