- Extra Credit HW 1.3 Naming, Drawing, & Measuring Angles, Segment & Angle Addition Name: Period: 1. Draw an angle with the given name: ZJWT 2. Name the angle in as many different ways as possible. Use a protractor to draw an angle with the given measure. 3. 190 4. 100* Use a protractor to find the measure of each angle and then describe each angle as acute, right, obtuse, or straight. 5. 7. D E Use the figure below for problems & & 9. 8. Name the obtuse angle. 9. Name two acute angles. 10. DF bisects ZCDE, DGbisects ZFDE, and #11. mZXWY is twice mZXWZ. Explain whether WZ MZCDG =$10. Find mZCDE. must be the angle bisector of ZXWZ. 12. An acute angle measures (6x-45)". Write an inequality to describe the range of all possible values of r. Find the indicated length, or solve for x. 13. 14. Find FG 2x -7 G R 13 19 16 21 15. 16. -16+ 25 Find my WIH if myJIW - 349 B and myJIN =930. r+6 17. Find x if MZRTV = 1 1x - 7, 18. Find x if MRST - 95%, MRSB - x + 31. "ZSTR = 2x + 16, and m/STU = 152". and m/BST = x +68. Use a definition, postulate, or theorem to find the value of x in the figure described. 19. Point E is between points D and F. If DE =x-4 20. SV is an angle bisector of ZRST. If , EF =2x+5, &DF =4x-8, find the value of x. MZRSV = (3x +5)" and m/RST =(8x-14)", find the value of x. 21. The figure shows a map of five streets that meet at Concord Circle. The measure of the angle formed by Melville Road and Emerson Avenue is 118". The measure of the angle formed by Emerson Avenue and Thoreau Street is 134". Hawthorne Lane bisects the angle formed by Melville Road and Emerson Avenue. Dickinson Drive bisects the angle formed by Emerson Avenue and Thoreau Street. What is the measure of the angle formed by Hawthorne Lane and Dickinson Drive? Explain your reasoning. Hawthome Ln. Emerson Ave. Melville Rd. concord Dickinson Dr. Thoreau St
