Lesson 2.3
Length of a Line Segment
A car accident has occurred approximately 50 km north of Sturgeon Falls. One of the victims
requires specialized surgery that is only performed at hospitals in Sault Ste. Marie, Toronto, and
Ottawa. A helicopter will fly the injured person directly to the closest of the three hospitals.
Where should the patient be flown?
1) How can we determine the distance from the accident site to each of the hospitals?
2) Would this method work if the accident site was not at the origin? Explain.

Derive the formula:
Length of a Line Segment:
1) A triangle has vertices at A(-1 , -1), B(2 , 0), and C(1 , 3).
a) Determine the lengths of the sides
b) Determine the slopes of the sides
c) Classify the triangle (i.e. what type of triangle is ∆ABC?)
