2.4.         Split Line Segment AB at Ratio 7:3

As GeoGebra allows us to calculate with vectors, this is an easy task. Type the following lines into the input field and press the Enter key after each line.

     A = (-2, 1)

     B = (3, 3)

     s = Segment[A, B]

     T = A + 7/10 (B - A)

Another way of doing this could be

     A = (-2, 1)

     B = (3, 3)

     s = Segment[A, B]

     v = Vector[A, B]

     T = A + 7/10 v

 

In a next step we could introduce a number t, e.g. by using a  Slider and redefine point T as T = A + t v (see  Redefine). By changing t you can see point T moving along a straight line which could now be entered in parametric form (see Line): g: X = T + s v
