Question

Use the distance formula, to calculate the ratio of a side length on DEF to the corresponding side length on ABC . Show your work. Then confirm your calculations using GeoGebra tools.

Answer 1

Answer: 1.5

Explanation:

DE=√(8-5)^2+(-0.5-1)^2 =√11.25≈3.35

AB=√(2-1)^2+(3-1)^2 =√5≈2.24

DE:AB ≈ 3.35 : 2.24 ≈ 1.5
