1. 1.) Write an equation to find the measure of ∠srz & ∠srn. Answer

2. #1.) Answer: m srn = 62° Equation: 5x - 27 = 3x + 31

3. The perimeter of a triangle is 39 inches. Side A is three time longer than Side B. Side C is six inches less than Side B. Write an equation to find each side length. Answer #2: Find A, B, and C

4. Equation: 3b + b + b – 6 = 39 A = 27 in. B = 9 in. C = 3 in. #2 Answer:

5. #3.) Write an equation to find the measure of the sum of the angles for the polygon below. Answer

6. #3.) Answer: Equation: d = 180(10 - 2) 1,440° DECAGON

7. #4.) Chris claims that if a shape has two sets of parallel lines, the shape has to be a parallelogram. Answer

8. #4 Answer Chris is correct because a rhombus, square, rectangle, and parallelogram all have this characteristic. Therefore, all of them are considered parallelograms.

9. #5.) Write an equation to find x and the 3 missing angles. 105 ° 100 ° (3x) ° 92° (2x + 40) ° 124 °

10. #5.) Answer: Equation: 2x + 40 + 2x + 40 + 92 + 105 + 3x + 124 + 100 = 900 x = 57 (2x + 40)° = 154° (3x)° = 171°

11. #6.) Adam marked a pair of alternate interior angles green and a pair of corresponding angles red. Is Adam correct? Answer p u n z

12. #6 Answer: Adam is not correct on both parts. He marked the pair of corresponding angles correctly, but not the pair of alternate interior angles. Alternate interior angles are congruent and on opposite sides of the transversal.

13. 7.) Write an equation to find the m∠wrb and m∠wrl. Answer

14. #7.) Answer: m ∠wrb = 32˚ m ∠wrl = 148˚ Equation: 6x + 4 + 2x – 16 = 180

15. 8.) Write an equation to find m∠ftb & m ∠btp. Answer P

16. #8.) Answer: m ∠ftb = 107° m ∠btp = 73° Equation: 5x – 18 = 4x + 7

17. #9.) Write an equation to find the # of sides in a polygon whose angle measures have a sum of 2,340°. Answer

18. #9 Answer: Equation: 2340 = 180(n – 2) 15 sides

19. 10.) Write an equation to find m lun & m lud. Answer p u n z d (3x – 35)° (2x – 12)°

20. #10 Answer m lun = 34° m lud = 146° Equation: 2x – 12 = 3x - 35

21. #11.) Name 3 things a trapezoid and a parallelogram have in common. Answer

22. #11.) Answer: 1.) They both have 4 sides. 2.) The sums of their angles are both 360°. 3.) They both have at least one pair of parallel sides.

23. #12.) If m 4 = 40°. What is the measurement of angle 5? Explain. 1 2 7 4 3 8 6 5 Answer

24. #12 Answer: because it is the alternate exterior angle to angle 4.

25. #13.) If m 4 = 40°. What is the measurement of angle 7? Explain. 1 2 7 4 3 8 6 5 Answer

26. #13 Answer: because it is a vertical angle to angle 4.

27. #14.) If m 4 = 40°. What is the measurement of angle 2? Explain. 1 2 7 4 3 8 6 5 Answer

28. #14 Answer: because it is a corresponding angle to angle 4.

29. #15.) If m 4 = 40°. What is the measurement of angle 3? Explain. 1 2 7 4 3 8 6 5 Answer

30. #15 Answer: because it is supplementary with angle 4.
