Question

line PM is the perpendicular bisector of seg AB ,AB=8cm and PA=6cm , then find the length of PB and hence perimeter of trianglePAB

Answer 1

Answer:

PB=6cm

Perimeter = 20cm²

Step-by-step explanation:

As PA = 6cm

     PB = 6cm  -  (common point from ends of a segment to perpendicular bisector are equidistant)

  perimeter = PA + PB + AB

                    = 8 + 6 +6

                    = 20 cm²
