Points and Vectors
From GeoGebra Manual
Points and vectors may be entered in Cartesian or polar coordinates (see Numbers and Angles).
Note: Upper case labels denote points whereas lower case labels refer to vectors.
Example: {{{1}}}
Note: You need to use a semicolon to separate polar coordinates. If you don’t type in the degree symbol, GeoGebra will treat the angle as if entered in radians.
In GeoGebra, you can also do calculations with points and vectors.
Example:
- You can create the midpoint M of two points A and B by entering
M = (A + B) / 2 into the Input Bar.
- You may calculate the length of a vector v using
length = sqrt(v * v)
