50. a. Using only a straight edge and a protractor draw two triangles that have the same interior angles-45, 35, and 100 as follows: Start with base sides of unequal lengths and using your protractor and straight edge construct different pairs of the above three angles at the two vertices formed by the ends of the base. Extend the arms of the angles until they meet at the third vertex. (Measure this angle-it should be equal to the missing third angle. Why?) b. Using your ruler carefully measure the sides of each triangle and calculate the ratios of sides opposite congruent angles in the two triangles. c. Does your conjecture in #44 hold true
