Name: ______________________ MAFS.4.MD Measurement and Data MAFS.4.G Geometry Practice-Test MAFS.4.MD.3.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement: a. b. An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles. An angle that turns through n one-degree angles is said to have an angle measure of n degrees. . MAFS.4.MD.3.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure. MAFS.4.MD.3.7 Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure. MAFS.4.G.1.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures. Question 1 [MAFS.4.MD.3.5] Multiple Choice An angle is shown. Choose the statement that is true about the angles shown. a) The name of Angle 1 is Angle FDE. b) The name of Angle 2 is Angle JHI. c) Ray DF is the side of Angle 1. d) The vertex of Angle 1 is E and the vertex of Angle 2 is I. Question 2 [MAFS.4. MD.3.7] Multi-Select A semi-circle is split into four equal angles as shown. The sum of the angle measures is 180º. Which equation can be used to find o? a. 180 ÷ 4 = o b. 180 − 4 = o c. 180 + 4 = o d. 180 × 4 = o Question 3 [MAFS.4.MD.3.6] Graphic Response Item Display Angle P measures 115. One ray of angle P is shown. Draw on the protractor to show another ray that will create angle P. Question 4 [MAFS.4. MD.3.7] Equation Editor Samuel and Jenna were kicking a ball as high as possible. Jenna kicked her ball at an angle of 126°. Samuel was able to kick his at an angle of 97°. What is the difference between the angles formed by their kicks? Question 5 [MAFS.4.MD.3.7] Equation editor Three rays meet at a point and form the angle shown. Write an equation measuring the angle a. Question 8 [MAFS.4.OA.3.5] Open response See the angle below. Describe how to find the measurement of the angle L. Question 6 [MAFS.4. MD.3.6] Multiple Choice What is the measure of this angle? Choose the best estimate. a) 60° b) 90° c) 135° d) 30° Question 7 [MAFS.4.MD.3.6] Open response Select the angles that measure 81° What is the measure of the angle? ________________ _______________________________ _______________________________ _______________________________ _______________________________ _______________________________ _______________________________ Question 9 [MAFS.4.G.1.1] Table Response A set of lines is shown. Select all the attributes that apply to each set of lines. Question 10 [MAFS.4. MD.3.6] Multiple Choice What is the value of j? ⓐ 42° ⓑ 46° ⓒ 98° ⓓ 18°
