Answer:
Step-by-step explanation:
Using Reflection, ADP and BCP are the same.
If line PD is equal to line PC, angle 1 is equal to angle 2 and angle 3 is equal to angle 4, then line AP is equal and a reflection of line BP, line AD is also equal and a reflection of line BC
In reflected angles, the sides and angles of the shape are not altered.
The original image and reflected shape above are same size and shape therefore triangle ADP and BCP are the same.
