8. A500 This quadrilateral has only one pair of parallel sides. Response: What is the trapezoid

9. A600 These are the three defining characteristics of a polygon. Response: What are Closed figure Made of line segments Only intersection is at vertices (no crossing)

10. A700 These are the quadrilaterals that have four congruent sides. Response: What are a square and a rhombus

11. A800 These are the defining features of a REGULAR polygon Response: What are congruent sides and congruent angles

12. A900 Beginning with the term ‘polygon’, these are all of the classifications of a SQUARE. Response: What is polygon quadrilateral parallelogram rectangle rhombus

13. A1000 This is the relationship of number of sides to number of angles in all polygons Response: What is The number of sides is always equal to the number of anglesin all polygons

14. B100 This is the formula for the perimeter of asquare. Response: What is P =4 x s (where s=length of a side)

15. B200 This is the formula for the perimeter of a rectangle. Response: What is P = (2xl) + (2xw) ? Where l=length and w=width

16. B300 This is the formula for the perimeter of a parallelogram Response: What is P= 2a + 2b (a=length of side b= length of base)

17. B400 This is the formula for the perimeter of any triangle. Response: What is P= a + b + c (where a,b,c are the sides of the triangle)

18. B500 This is the formula for the perimeter of an equilateral triangle. Response: What is P = 3 x s (where s = length of one side)

19. B600 These are 2 of the formulasto find the perimeter or circumference of a circle. Response: What are C = π d C = 2 π r (where d= diameter and r = radius)

20. B700 This is the formula for the perimeter of any irregular polygon. Response: What is P = s1+s2 +s3 +…sn (where s= length of side n= number of sides)

21. B800 This is the formula for the perimeter of any trapezoid. Response: What is P = a + b + c + d (where b = base and a,c,d = all other sides)

22. B900 This polygon has a perimeter formula the same as that of a square. Response: What is A rhombus ( P = 4 x s)

23. B1000 This is the formula for the perimeter of any regular polygon. Response: What is P=n x s Where n= the number of sides s= the length of each side

24. C100 This is the formula for the area of a square. Response: What is A = S2 Where s = length of side

25. C200 This is the formula for the area of a rectangle. Response: What is A = l x w Where l = length and w = width

26. C300 This is the formula for the area of a triangle. Response: What is A= (b x h) ÷ 2 (where b = the base of the triangle and h = the height of the triangle)

31. C800 This is one method for finding the area of this compound figure. Response: What is divide it into 2 measureable figures and find the area of each; then add those areas together.

32. C900 This is a process of finding the radius of a circle is the Area measurement is given. Response: What is Taking the square root of A ÷ π

33. C1000 To apply the formula for the area of a parallelogram, you must find the height by doing this. Response: What is draw a perpendicular line from the base of the parallelogram to a vertex in base2
