Question

use common sense to determine whether the given event is possible. the three vertices on a triangle lie on a straight line. (1 point) ∘ it is impossible. ∘ it is possible and likely. ∘ it is possible, but very unlikely.

Explanation:

A triangle is defined as a polygon with three non - collinear vertices (vertices not on the same straight line) that are connected by three line segments. By the very definition of a triangle, having all three vertices on a straight line would mean the figure is a straight line segment (a degenerate form that doesn't meet the definition of a triangle). So, the event of the three vertices of a triangle lying on a straight line is impossible.

Answer:

It is impossible.
