Because since rs Is equal to qr since r is the midpoint of qs. So qr is 8 and because s is the midpoint of the whole line. I multiply it by 2. Giving me 16 for the whole line
Angle 1 and Angle 2 are alternate interior angles, meaning they are congruent to one another. You can tell they're alternate interior angles because they are located between the two parallel lines but on opposite sides of the transversal.
