LINES AND ANGLES
interior angles on the same side of the transversal are equal. Will the two lines always be parallel? Give reason for your answer. Solution : In general, the two lines will not be parallel, because the sum of the two equal angles will not always be 180°. Lines will be parallel when each equal angle is equal to 90°. EXERCISE 6.2 1.
