Honors Geometry – Midpoint & Distance
Notes: Finding midpoint and distances given two points.
Step 1: Plot the points (1,2), (4,2) and (4,6) on the graph provided.
Connect to form a right triangle.
Step 2: Verify your measurement by Pythagorean Theorem to
find the distance between the points.
Step 3: Estimate the midpoint. Use the ruler to estimate the location of the point halfway between (1,2) and (4,6). What are the coordinates of this point? ___________
Step 4: Find the mean of the corresponding coordinates.
Find the mean of the x-coordinates of the points (1,2) and (4,6). _______
Find the mean of the y-coordinates of the points (1,2) and (4,6). _______
How do these compare with the answer in step 3? _____________________
Examples:
1. Explain how you can use the Pythagorean Theorem to find the
distance between any two points in a coordinate plane.
Use the extra graphs to plot the coordinates if needed. SHOW ALL WORK!
Find the distance between the two points
2. (7, 2), (-2, 10) 3. (-3, 6), (2, -6) 4. (x1,y1), (x2,y2)
5. Explain how you can find the midpoint of the line segment joining any
two points in a coordinate plane.
Find the midpoint of the line segment joining the two points.
6. (7, 2), (-2, -10) 7. (-3, 6), (2, -6) 8. (x1,y1), (x2,y2)
