Question

Delilah drew 3 points on her paper. When she connects these points,must they form a triangle? Why or why not?

Answer 1

No.

Explanation:

The points may be in a straight line, and that doesn't form a triangle.

Answer 2

If the three points all fall on the same straight line, then a triangle will not form. Instead, a line will. We call these points to be collinear.

If the points aren't collinear, then a triangle forms.
