Question

I believe I can find the angles once I have the lengths, but I'm not sure how to use the points of A, B & C to find the length of each side in this 4-dimensional scenario. (see image)

2.) Let A = (-4, 6, 3, 7), B = (-1,-1, 2, 3), and C = (-1, 7, 1, -2). These form a triangle, AABC in R4. (a) Find the lengths of each side of AABC. Remember: (-4, 6, 3, 7) is the location of a vertex of the triangle. It is not a vector that comprises a side of the triangle. (b) Find the measure of each of the angles of AABC. Verify that they sum to 180°.
