dist3: Distances and the Pythagorean Theorem (Single-Choice)

Exercise template for computing the distance (single-choice) between two randomly-drawn points in a Cartesian coordinate system.

Name:
dist3
Type:
schoice
Related:
dist, dist2
Description:
Computing the (Euclidean) distance between two randomly-drawn points by using the Pythagorean Theorem. In addition to the correct solution, four false alternatives are generated through num_to_schoice() by providing two common errors along with a range and minimal delta for two further random solutions.
