Shapes and Design Unit Review

1. Use the diagram of the polygon below. Estimate the measures of each angle. 2. Jose drew this shape. What is true regarding his shape? Select all that apply. The shape is a polygon. Angle A is acute. Angle B is acute. Angle A is complementary to angle B. Angle B is supplementary to angle C. 3. Sort the shape into the correct category. Can Tile a Surface Cannot Tile a Surface 4. Find the measure of the angle x. 109 5. Could a quadrilateral have two sides of length 6, one side of length 13.5, and one side of length 1.5? Explain why or why not? 6. If the measure of angle 1 is 25º, what is the measure of angle 2, angle 3 and angle 4? measure angle 2= 40measure angle 3= 65measure angle 4= 70 7. Two parallel lines are cut by a transversal. Find each angle measure. 75 105 105 75 8. Write the letter of each shape in the appropriate category. Write your answer in capitals. Rotational Symmetry F Reflectional Symmetry E Has Both Symmetries B C D No symmetries A 9. Tell whether each figure has reflectional symmetry. If it does, draw the line(s) of symmetry. If not write none. 10. Tell whether each figure has reflectional symmetry. If it does, draw the line(s) of symmetry. If not write none. 11. Tell whether the figure has reflectional symmetry. If it does, draw the line(s) of symmetry. If not, write none. 12. Find the measure of the angle indicated in bold. 13. Identify each pair of angles Corresponding angles Alternate exterior Alternate interior Consecutive angles 14. Find the angle measure. 60 15.
