What kind of triangle on its sides form the vertices (0, –5. 5), (1, –2, 4), (3, 4, 2). B) Calculate your area. Explain result.

4. Consider the following figure: A(1,1,0) D B(-1,-1,-1) C(2,2,0) a) Find the coordinate of D if ABCDis parallelogram b) Calculate the area of parallelogram.

Find the area of the triangle with vertices P(1, 0, 1), Q(-2, 1, 3) and R(4, 2, 5). Show work for full credit.

Use the cross product to find the area of the triangle with the vertices P = (3, 3,7), Q = (5,6, 5), and R = (3,7,9) in the figure R (Use symbolic notation and fractions where needed.) A =
