1. The problem statement, all variables and given/known data The vertices of a figure are given by A(-8, 4, -2), B(-6, 3, 5), and C(-10, 5, -9). What type of figure is ABC? Why? 2. Relevant equations pythagorean theorem: |AB|=√(x^2+y^2+z^2) 3. The attempt at a solution I first found the vector AB, BC, and CA by subtracting the components of the vectors. Then I calculation the magnitude of |AB|, |BC|, and |CA| using the pythagorean theorem. I got this |AB|=3√6 |BC|=6√6 and |CA|=3√6 According to my calculation, point A is on the line connecting points B and C, so the 3 points are collinear and form a line. But the answer seems wrong since they are asking for a type of a figure.
