501 Geometry Questions

Set 18

93. Since ∠PIL is bisected by ∠RIL, we know that ∠PIL is divided
    into two equal angles. Therefore, since m∠RIL = 68°, it follows
    that m∠PIL = 68°.


94. Since ALis a straight angle, then m∠AIL = 180°. Subtract ∠PIL
    from 180 ° in order to find m∠PIA. 180° – 136° = 44°. Therefore,
    m∠PIA = 44°.
