CCSS IP Math III 5.7.1 Example 4

A right triangle is defined as a triangle with 2 sides that are perpendicular. Triangle [i]ABC[/i] has vertices [i]A[/i] (–4, 8), [i]B[/i] (–1, 2), and [i]C[/i] (7, 6). Determine if this triangle is a right triangle. When disproving a figure, you only need to show one condition is not met.

[list=1] [*]Plot the triangle on a coordinate plane. [*]Calculate the slope of each side using the general slope formula. [*]Observe the slopes of each side. [*]Make connections.
