## 4.2. Direct Input

GeoGebra can treat numbers, angels, points, vectors, segments, lines, conic sections, functions, and parametric curves. We will now explain how these objects can be entered through coordinates or equations into the input field.

Note: You can also use indices within the names of objects, for example A1 or SAB is entered as A_1 or s_{AB}.
