Triangles Exercise 6.6 Class 10 Maths
Q.1. In the given figure, PS is the bisector of ∠QPR of ∆PQR. Prove that QSSR=PQPR.
Solution:
Given that, PS is angle bisector of ∠QPR.
Construct a line RT parallel to SP which meets QP produced at T. ∠QPS=∠SPR ……(1) ∠SPR=∠PRT
(As PS||TR, alternate interior angles) ….(2) ∠QPS=∠QTR (As PS||TR, corresponding angles)
…..(3) Using these equations, we may find ∠PRT=∠QTR from (2) and (3) So, PT=PR (Since ΔPTR is
isosceles triangle)
Now in ΔQPS and ΔQTR, ∠QSP=∠QRT (As PS||TR)
∠QPS=∠QTR (As PS || TR)
∠Q is common. ΔQPS~ΔQTR (by AAA property) So, QRQS=QTQP ⇒QRQS-1=QTQP-1 ⇒SRQS=PTQP
⇒QSSR=QPPT ⇒QSSR=PQPR
Q.2. Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m above the surface of the water and the fly at the end of the string rests on the water 3.6 m away and 2.4 m from a point directly under the tip of the rod. Assuming that her string (from the tip of her rod to the fly) is taut, how much string does she have out (see the given figure)? If she pulls in the string at the rate of 5 cm per second, what will be the horizontal distance of the fly from her after12 seconds?
Solution:
Let AB be the height of tip of fishing rod from water surface and BC be the horizontal distance of fly from the tip of fishing rod.
Then, AC is the length of string. AC can be found by applying Pythagoras theorem in ΔABC. AC2=AB2+BC2
AC2=1.82+2.42 AC2=3.24+5.76 AC2=9.00 Thus, length of string out is 3 m.
Now, she pulls string at rate of 5 cm per second.
So, string pulled in 12 second=12×5=60 cm=0.6 m.
After 12 seconds, let us assume the fly to be at point D.
Length of string out after 12 second is AD. AD=AC- string pulled by Nazima in 12 second =3.00-0.6 =2.4 m In ΔADB,
AB2+BD2=AD2 ⇒1.82+BD2=2.42 ⇒BD2=5.76-3.24=2.52 ⇒BD=1.587 m Horizontal distance of fly =BD+1.2
=1.587+1.2 =2.787 =2.79 m
Q.3. In the figure, D is a point on hypotenuse AC of ∆ABC, such that BD⊥AC, DM⊥BC and DN⊥AB. Prove that : DM2=DN.MC
Solution:
Let us join DB.
DN||CB, DM||AB
Therefore, DNBM is a parallelogram.
Since, ∠B is 90°, therefore, DNBM is a rectangle. Hence, DN=MB, DM=NB and ∠CDB=∠ADB=90°
∠2+∠3=90o…(1) In ΔCDM ∠1+∠2+∠DMC=180° ∠1+∠2=90°…(2) In ΔDMB ∠3+∠DMB+∠4=180°
∠3+∠4=90°…(3)
From equation (1) and (2)
∠1=∠3
From equation (1) and (3) ∠2=∠4 So, ΔBDM~ΔDCM BMDM=DMMC ⇒DNDM=DMMC ⇒DM2=DN.MC Hence, proved.
