Is it possible to draw a triangle with sides measuring 13, 21, and 39? Explain |
| |
|
A. |
Yes; the sides of the triangle are not all the same lengths. |
| |
|
B. |
No; 39 is greater than 13 + 21. |
| |
|
C. |
Yes; 13 + 21 is less than 39. |
| |
|
D. |
No; 13 is less than 21 + 39. |

2. |
Refer to the figure. Which statement is never true? |
| |
|
 |
| |
|
A. |
If is obtuse, then EG > EF. |
| |
|
B. |
If EG = 6, ED = 8, and then FG = DF. |
| |
|
C. |
If DF = 20, FG = 13, and EG = 15, then EF = 11. |
| |
|
D. |
If FG = 4, EGDE = 6, then EF < 18. |

5. |
Is it possible to draw a triangle with sides measuring 32, 96, and 118? Explain. |
| |
|
A. |
No; 32 + 96 is less than 118. |
| |
|
B. |
Yes; the sum of the measures of any two sides is greater than the other side measure. |
| |
|
C. |
No; 32 is less than 96 + 118. |
| |
|
D. |
Yes; 96 is between 32 and 118. |
