Use the information below to answer the questions
D is the midpoint of AB
E is the midpoint of AC
DE is the midsegment of triangle ABC
Part 1
1. Find the length of DE by using the distance or length tool then clicking on DE.
2. Repeat this process to find the length of BC.
Is there anything you notice about the relationship between the two lengths you just found?
To see if this is always true, drag either point B or point C so that the length of BC and DE change. (You may need to click the point tool first)
Record five difference combinations
Length of DE Length of BC
Part 2
As you move point B or C around, what do you notice about the slopes of the two segments? What do they appear to be?
To determine if this is true, use the slope tool to find the slope of DE and BC
Again drag point B or C around and record five combinations of slopes
Slope of DE Slope of BC
