15. 15. Complete the sentence. LAE
16. 16. Complete the sentence. LAE 1
17. 17. Complete the sentence. LAE 1
18. 18. Complete the sentence. LAE 1 180
19. 19. Without measuring sketch each angle, then measure for accuracy. Each angle is half of 90 or 45 150 = 90+60 150 = 90+30+30
20. 20. Draw a line, . Choose a point O between A and B. Use a protractor to investigate the following questions. Q23. In a plane represented by your paper, how many lines can you draw through O that will form a 30 0 angle with ? A O B 2
21. 21. Draw a line, . Choose a point O between A and B. Use a protractor to investigate the following questions. Q24. In a plane represented by your paper, how many lines can you draw through O that will form a 90 0 angle with ? A O B 1
22. 22. Q25 Using a ruler, draw a large triangle. Then use a protractor to find the approximate measure of each angle and compute the sum of the three measures of each angle. Repeat the exercise. Do you get the same result? Sum = 180 0 Sum = 180 0 Yes
23. 23. Q26 Find the measures of angle 2, 3, & 4 when the measure of angle 1 = 90. Q27 Find the measures of angle 2, 3, & 4 when the measure of angle 1 = t. Note that adjacent angles add up to 180 0 .
