Points and vectors may be entered via Input Bar in Cartesian or polar coordinates (see Numbers and Angles). Points can also be created using Point tools, Vector from Point Tool, Vector between Two Points Tool and a variety of commands.
- To enter a point P or a vector v in Cartesian coordinates you may use
P = (1, 0) or v = (0, 5).
- In order to use polar coordinates type in
P = (1; 0°) or v = (5; 90°).
In GeoGebra, you can also do calculations with points and vectors.
- You can create the midpoint M of two points A and B by entering
M = (A + B) / 2into the Input Bar.
- You may calculate the length of a vector v using
length = sqrt(v * v)
- If A = (a,b), then A+1 returns (a+1,b+1). If A is a complex number a+bi, then A+1 returns a+1+bi.
