3. TRUE or FALSE? Side lengths of 6 in.,13 in., and 17 in., can make a triangle. According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side. As 6 + 13 = 19, these side lengths WILL make a triangle.

4. Find the value of x and each of the angle measures X= 69 42 138

5. TRUE or FALSE? Side lengths of 2 in.,5 in., and 3 in., can make a triangle. According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side. As 3 + 2 = 5, these side lengths will NOT make a triangle.

6. Solve the inequality and graph the solution: -4x > -36 -4 -4 x > 9

7. Find the value of x and each of the angle measures

8. If a triangle has side lengths of 5m and 9m, what is the range for the possible side lengths of the third side? According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side. The third side must be larger than 4 BUT Less than 14

9. Solve the inequality and graph the solution: 9x ≤ 54 9 9 x ≤ 6

10. Find the value of x and each of the angle measurements. 16° 4(41°)=164°

11. If a triangle has side lengths of 7 cm and 8 cm, what is the range for the possible side lengths of the third side? According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side. The third side must be larger than 1 BUT less than 15.

12. TRUE or FALSE? Two side lengths of 8 in and a third side length of 15 inches can make a triangle.

13. The Figures A and B below are similar. Find the missing side length on Figure B below. Figure A 6 in 9 in Figure B x 6 in

14. If a triangle has side lengths of 18 m and 12 m, what is the range for the possible side lengths of the third side? According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be larger than the third side. The third side must be larger than 6 BUT less than 30 make a triangle.

15. Find the value of x and each of the angle measurements.

16. Originally included slides not used in quiz…

17. What is the scale factor (the multiplier) from figure A to figure B below? Figure A 2 cm Figure B 7 cm

18. TRUE or FALSE? Two acute angles and one obtuse angle can make a triangle

19. The Figures A and B below are similar. Find the missing side length on Figure A below. Figure A x 10 mm Figure B 1 mm1 mm 4 mm4 mm

20. A triangle with no congruent sides A triangle with all angles congruent A triangle with all angles measuring less than 90 o A triangle with only two sides congruent A triangle with one angle measuring more than 90 o Obtuse Acute Scalene Equiangular Isosceles Match a triangle on the right to the best description of that triangle on the left.

21. If a right triangle has a side length of 3ft and one angle measure of 42 o, what is the angle measure of the third side? Triangles total 180 o for their interior angles. A right triangle has one angle equal to 90 o and two acute angles. So, 180 o – 90 o – 42 o = missing angle in this triangle.

22. TRUE or FALSE? Two obtuse angles and one acute angle can make a triangle

23. TRUE or FALSE? A triangle has side lengths of 30 o and 50 o. This triangle might be an acute triangle.
