You are given the coordinates of three points that are the vertices of a triangle. you need to determine if the triangle is a right triangle. explain how you could determine this.

Let A, B, C be the three points. Let

be the slopes of the lines AB, BC and AC, respectively. We can compute those slopes using the "rise over run" formula:

Now, the triangle is a right triangle if and only if two of its sides are perpendicular. And two lines are perpendicular if and only if their slopes are in the following relationship:

So, all you need to to is to find the slope of the three sides (by dividing the difference between the y and x coordinates), and then check all the pairs: if a pair of slopes give -1 when multiplied, then the triangle is a right triangle.

step-by-step explanation:

most likely the answer is a.
