1.5 Segments and Congruence
Instructions
1. Add a new point (C) on line AB to the left of point A.
2. Use the measure tool to find the length of segment AB.
3. Move your new point so that it is between point A and B.
4. Find the length of AC and AB and place them on sketch.
How long is AB?
Part 2: Instructions
1. Move C so that AC and CB change. Then, make at least 5 points on the graph where x=AC and y=CB.
2. Use the Best Fit Line to find the a line that goes between the points. Add a label that shows the equation of the line.
Your line should have the form where A and B are close to the same. Average A and B and use the value for both. What is this equation of your line?
Divide both sides of the equation by the coefficient of x and y and record it here. What does the equation mean?
