11. Square

12. Give all the names of the polygon.

14. Give all the names of the polygon.

16. A) Name the polygon. B) Find the measure of one angle

17. A) Pentagon 180 (n-2) 540/5 = 108° 180 (5-2) 180 (3) 540

18. A) Name the polygon. B) Find the measure of one angle

19. A) Octagon 180 (n-2) 1080/8 = 135° 180 (8-2) 180 (6) 1080

20. A) Name the polygon. B) Find the measure of one angle

21. A) Heptagon 180 (n-2) 900/7 = 128.6 102.86° 180 (7-2) 180 (5) 900

22. Find the value of x. 72° x° 108° 72°

23. 72 + 72 + 108 + x = 360 252 + x = 360 X = 108°

24. Find the value of x. 102° x° 2x° 90°

25. 102 + 90 + 2x + x = 360 192+ 3x = 360 3x = 168 X= 56°

26. Find the area of the polygon.

27. A= ½ bh A = ½ (7) (6) A = 21 cm2

28. Find the area of the polygon.

29. A= bh A = (7) (8) A = 56 cm2

30. Find the area of the polygon.

31. A= ½ h (a + b) A = ½ (10) (7 + 15) A = 110 cm2

32. Find the base of a triangle with an area of 44 ft2 and a height of 22ft. A= ½ bh 44 = ½ b (22) 44 = 11b 4 ft = b

33. Find the area of the circle.
