Answer:
Given,
AD is bisector of angle BAC
=> angle CAP = angle BAP
angle CPD = angle BPD
=> 180° - angle CPD = 180° - angle BPD
=> angle CPA = angle BPA (linear pairs)
To prove: ∆CAP ~= ∆BAP and CP = BP.
Proof:
In ∆CAP and ∆BAP,
angle CAP = angle BAP (given)
angle CPA = angle BPA (proved)
AP = AP (common)
Therefore, ∆CAP ~= ∆BAP by ASA congruence.
=> CP = BP (Corresponding parts of congruent triangle).
