When coordinates can be introduced in an affine geometry the two definitions of midpoint will coincide. In triangle ADE and ECF we have DE EF by construction AED CEF since they are vertically opposite angles and EC AE since E is the midpoint of AC. In the above figure length of is 15 cm and distance of C from both the endpoints A andB is 75 cm.
In the above figure length of is 15 cm and distance of C from both the endpoints A andB is 75 cm.
In Coordinate Geometry there are several ways to find the midpoint of a line segment. Try this Adjust the line segment below by dragging an orange dot on an endpoint and see how the point M always divides the segment PQ into two equal halves. A point on a line segment that divides it into two equal partsThe halfway point of a line segment. Look at the blue line going from 00 to 30.
