The plane that passes through (6, 0, -4) and contains the line x = 3 - 3t, y = 2 + 5t, z = 3 + 3t. Write the equation of the plane that contains the two lines {x+1}{5} = {y-3}{-2} = {z}{3} \enspace and \enspace {x-5}{5} = {y-2}...
Proof that the sum of the angles in a triangle is 180 degreesAccording to an ancient theorem, a transversal through two parallel lines (DEandABin the figure) forms several equal angles, such as the alternating angles α/α' and β/β', labeled in the figure. By definition, the three angl...
