Prove c is the midpoint of AQ
Answers
In APQ
B is midpoint of AB
BC is parallel to QP
C is midpoint of AQ
(midpoint theorem)
C is the midpoint of AQ, AC = CQ
Perimeter of quadrilateral BCQP is 33 cm.
Step-by-step explanation:
Given :
ABCD is parallelogram
AB=BP
PQ ║BC
AB = 8 cm, AD = 5 cm, AC = 10 cm
- To Prove C is the midpoint of AQ
- To find perimeter of quadrilateral BCQP
To Prove C is the midpoint of AQ, AC = CQ
Lets consider Δ APQ
AB = BP = 8 cm (given)
Hence B is the midpoint of AP
PQ ║BC (given )
According to the midpoint theorem,
AC = CQ = 10 cm ...... (1)
Thus its proved that C is the midpoint of AQ.
To find perimeter of quadrilateral BCQP
Perimeter of the quafrilateral BCQP = BC + CQ + QP + BP
BC = 5 cm ( AD = 5 cm , AD = BC as ABCD is a prallelogram)
CQ = 10 cm (from equation (1))
BP = 8 cm (given)
Let QP be X
In Δ ABC and Δ APQ
(AP = AB+BP = 8 + 8 = 16 cm)
8X = 5 x 16
∴ Perimeter = 5 + 10 + 10 +8 = 33 cm
