Segment AD must be congruent to segment DC
Segment BC must be congruent to segment AB
What is SAS rule of congruency?
If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.
Given
Line AC and passes through B which is the midpoint of AC
To show that PA=PB
In △DCB and △DAB
AB=BC since B is the mid-point of AC
∠DBA=∠DBC=90 (given)
DB = DB (common)
So,△DCB≅△DAB by SAS rule.
and so AD=DC as they are corresponding sides of congruent triangles.
BC=AB as they are corresponding sides of congruent triangles.
