Lines a and b in the diagram are parallel. Parallel lines a and b are cut by 2 transversals. At the intersection of line a with the transversals, clockwise from top left, the angles are 45 degrees, 95 degrees, blank, blank, B, 40 degrees. At the intersection of b with a transversal, the angles are blank, A, blank, blank. At the intersection of b with the second transversal, the angles are C, blank, blank, blank. Step 1: measure of angle A = 40 degrees (alternate interior angles). Step 2: measure of angle B = 95 degrees (vertical angles). Step 3: measure of angle C = 40 degrees (corresponding angles). Shalini found the sum of the measures of the interior angles of the triangle to be 175°. She knows the sum is supposed to be 180°. What was Shalini’s error? m∠A = 45° m∠B = 85° m∠C = 45° Shalini did not add the sum of the 3 angles correctly.
