Geometry District Assessment #10 Review Name_________________________ (Links to State Standard GE 12.0) (Use after Chapter 11.1) Date_______________Period _____ GE 12.0* Students find and use measures of sides and of interior and exterior angles of triangles and polygons to classify figures and solve problems. For questions 1 through 6, calculate the following for each regular polygon described below: a. The sum of the interior angles b. The measure of each interior angle c. The measure of each exterior angle 1. An equilateral triangle: 2. A square: a. a. b. b. c. c. 3. A regular pentagon: a. 4. A regular hexagon: a. b. b. c. c. 5. A regular decagon: a. 6. A regular 15-sided figure: a. b. b. c. c. 7. A regular polygon has interior angles that measure 150˚ each. How many sides does the polygon have? 8. A nonagon has nine sides. What are the measures of each exterior angle of a regular nonagon? 9. Three of the interior angles in a pentagon measure 100˚ each. If the other two angles are congruent, what are the measures of each of the remaining angles? 10. ABCD is a quadrilateral. What is the measure of x ?
