INB 15 Segments & Midpoints

INB 14 Part 1 Processing Midpoints of Segments (boss/secretary) Part 2 Segment Addition practice page 8

INB 17 Midpoints with Coordinates

After some sharing of how to find the midpoints with graph paper – another student suggested he added the coordinates, then divided by 2.

Find M, the midpoint of AB.  A(7, 3) and B (13, 5)…

x-coordinates:  7+13=20 / 2 = 10 and y-coordinates:  3 + 5 = 8 / 2 = 4 so the midopint will be M(10, 4)

*Love this question – if you average your x’s & y’s to get the midpoint of a segement.  What if you average your x’s & y’s for a triangle:  Will that give you the “midpoint” or center of the triangle?

My response – Let’s See…

Hmmm.
