Points, Lines, Planes in 3D
1). Drag the points from the origin to the required position to complete Task 1. Tick to show only the points you need for each part of the question. You will find the first and last toolbar buttons useful. Once you see a shortcut you do not need to use Geogebra anymore. 2). Enter an equation in the INPUT bar (below) to complete Task 2. You can "refresh" and reset the coordinate system after every question.
