Write your answers to the short response question in the space provided. For each short response question, use the grid provided to create any required charts or graphs. If a question does not require a chart or graph, write your written response over the grid lines. 21. Look at the figure below. A. How many lines of symmetry does the figure have? B. Draw all the lines of symmetry on the figure below. 21. A. The figure (a polygon known as a hexagon) has 6 lines of symmetry. OPEN RESPONSE QUESTION Directions: Read all parts of each open response question before you begin. Write your answers to the open response questions in the space provided. For each open response question, use the grid provided to create any required charts or graphs. If a question does not require a chart or graph, write your written response over the grid lines. 22. Caroline drew the shape below. A B C E D A. Describe ALL of the angles in the shape. B. Does the shape have any parallel or perpendicular sides? Explain your answer. C. Name the shape that Caroline drew. 22. A. Angle A is a right angle (90º). Angle B is an obtuse angle (greater than 90º). Angle C is an acute angle (less than 90º). Angle D is an obtuse angle (greater than 90º). Angle E is a right angle (90º). B. Parallel sides never meet or touch. Line segment AB is parallel to line segment ED. Perpendicular sides meet (intersect) and create 90º angles. The shape has 2 sets of perpendicular sides. Line segment BA makes a right angle (90º) with line segment EA. Line segment AE makes a right angle (90º) with line segment DE. C. The shape Caroline drew is a polygon known as a pentagon with 5 sides.
