Three line segments have the following measures: AB=6, BC= 3, and AC=8. If A,B, and C are distinct points, what conclusions can you draw about points A,B, and C? Draw a diagram and explain your answer.
If AC were 9, the points would lie in a straight line.
But, since AC is shorter, point B has to rise out of the line, making ABC a triangle.
