Given
- E = -17
- F = -10
- G = 1
- H = 8
- I = 14
- units in cm, all on a number line
Find
- The length of FI
- Two segments that are the same length
Solution
1. The distance from F to zero is 10. The distance from zero to I is 14. Those distances add to give the distance ...
... FI = 10 cm + 14 cm
... FI = 24 cm
2. The coordinates E and F differ by 7, as do the coordinates G and H. One pair of equal-length segments that are 7 cm long is {EF, GH}.
Segment FG can be added to each of those to make another pair of equal-length segments that are 18 cm long: {EG, FH}.
