Question

The measures of three line segments are given in each set.

Which set of line segments cannot form a triangle?


20.2 m, 20.4 m, 20.6 m

32.8 m, 48.2 m, 81.1 m

12.8 m, 25.7 m, 35.9 m

35.6 m, 49.9 m, 83.2 m

Answer 1

second option: 32.8 m, 48.2 m, 81.1 m

Explanation:

20.2 m + 20.4 m = 40.6 m. which is bigger than 20.6 m. so yes

32.8 m + 48.2 m = 81 m. which is smaller than 81.1 m. so no

12.8 m + 25.7 m = 38.5 m. which is bigger than 35.9 m. so yes

35.6 m + 49.9 m = 85.5 m. which is bigger than 83.2 m. so yes
