Exercise 1.12. Determine the cosine of the angles of the triangle whose vertices are A = (2,-1, 1), B = (1, -3, -5) and C = (3,-4,-4).

Hi I need help with reviewing geometry. I'm not sure how to do reflections across the x and y-axis.

Consider the parallelogram. If the parallelogram is rotated 90 clockwise with the center of rotation at the origin, which best describes the resulting figure? The resulting figure will be a rectangle because all angles will be 90°, but not all sides are equal. O The resulting figure will be a square because all angles will be 90°, and all sides are equal. O The resulting figure will still be a parallelogram because rotations preserve parallel lines. The resulting figure will not be a parallelogram because rotations do not preserve parallel lines.
