Section 2.4 Quiz on Vectors in 3D

Figure 2.4.1. A screenshot from the Quiz on 3D Vector Geometry
In this quiz, the user will answer questions about vector geometery and calculations based only on the graph of the vectors. The vectors in this lesson are randomly generated, so the user has the option to generate another random set of vectors if they are not able to easily distinguish or select correct options. The first two questions related to the cross product of two vectors incorporates visual and verbal descriptions of the right hand rule for cross products. Additional questions ask about the sign of a dot product, as well as the sum, difference, and linear combination of vectors from a geometric perspective.
