The problems are based on standards from the National Council of Teachers of Mathematics and state standards from across the nation. Practice pages include problems in Number and Operations, Algebra, Geometry, Measurement, and Data Analysis and Probability. Each section features a test for assessment and essential mathematical vocabulary terms for success. Problem solving is embedded throughout. One word problem on most pages requires a written response on a separate piece of paper. The activities may be used at any time of the year to assess understanding, for additional practice, or for test preparation. MASTERING THE STANDARDS: GEOMETRY 1 Name Date Practice Assessment: Lines and Angles In the figure to the right, name four angles. 1.______ 2.______ 3.______ 4.______ F Using a protractor, measure the angles you named in the above problems. 5.______ 6.______ 7.______ 8.______ Give the complementary and supplementary angle to the angles measured. 9. ______ ______ 12. ______ ______ 10. ______ ______ 13. ______ ______ 11. ______ ______ Lines m and n are parallel and line l is a transversal. In this figure, name the following: 14.All pairs of corresponding angles_________ 15.All pairs of alternate interior angles_ ______ 16.All pairs of alternate exterior angles_______ l In the figure to the right, give a reason _why each statement is true. 17.∠UPO ≅ ∠WPV_______________________ 18.∠WPU ≅ ∠WOS______________________ 19.∠WPU ≅ ∠ROT_______________________ 20.∠UPO ≅ ∠TOR_______________________ No. AM109R © Copyright 2008, Hayes School Publishing Co., Inc. 3 Name Date Points, Lines, and Planes Use the figure at the right. Name each of the following. 1.Four segments that intersect AB______________________ 2.Three segments parallel to AB _ _____________________ 3.Four segments skew to AB _ ________________________ 4.Two planes with edge AB ___________________________ Use the figure at the right. Name each of the following. 5.All points________________________________________ 6.Six line segments_ ________________________________ 7.Four rays________________________________________ 8.Two lines________________________________________ Write an equation that expresses each length. Then find the length of each line segment. 9.equation: ______ x = ______ AB ______ AC _____ 10.equation: ______ n = ______ LM ______ MN ______ 11.equation: ______ y = ______ RS______ ST______ No. AM109R © Copyright 2008, Hayes School Publishing Co., Inc. 4 Name Date Intersections point C on line AB AB point R at the start of ray RT RT points M and N at end of line segment MN MN C R T M N Points are at intersections of lines, line segments, and rays. With intersections, angles are formed. Angles are named in several ways: angle ABC (∠ABC) angle CBA (∠CBA) angle B (∠B) angle 2 (∠2) Name the figure and write the symbol for it. 1. 3. ____________________________ ____________________________ 2. 4. ____________________________ ____________________________ Name each angle in four ways. 5. 7. ____________________________ 6. ____________________________ 8. ____________________________ ___________________________ Give four examples of intersecting lines.
