What is the perimeter of a triangle with the vertices (0,7) (0,1) and (4,7)
Use your knowledge of parallel lines and a transversal to find the measures of all the following angles. (HINT: Do not try to go in numeric order. Start with one value and find the vertical angles, supplementary angles, corresponding angles, alternate interior angles, and alternate exterior angles.But, please enter your answer in numeric order.)

The angle between the position T1,(62.5) and T2,(58.5), should be twice the prism angle, (60.5). Use the theorem from geometry that says that the measure of the central angle of a circle is twice that of the corresponding inscribed angle, to show why this is so.
