I was hoping if you could help me to solve this problem. Thank you. A department wants to schedule final exams so that no student has more than one exam on any given day. There are 7 vertices of degrees 3,3,4,4,4,5,6 which show the courses that are being taken by more than one...

Triangle ΔABC has vertices A(2,5), B(8,1) and C(-2,-1) and is a right triangle. If the slope of AB is -2/3 and the slope of AC is 3/2, are the lines parallel, perpendicular or neither?

Apply the rule (2x, 0.5y) to the vertices of triangle ABC to get triangle FGH. Compare the corresponding measurements (side lengths, perimeter, area, angle measures) of the two triangles.
