(1) The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\))




Activity :

r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.

A(P-AXB) = \(\frac{\theta}{360} \times \framebox[1cm]{\phantom{X}}\)


= \(\frac{\framebox[1cm]{\phantom{X}}}{360} \times 3.14 \times 10^2\)


= \(\frac{1}{4} \times \framebox[1cm]{\phantom{X}}\)


A(P-AXB) = \framebox[1cm]{\phantom{X sq. cm.

In the following figure chord MN and chord RS intersect at point D. If RD = 15, DS = 4, MD = 8, find DN by completing the following activity:




Activity :
\(\therefore\) MD \(\times\) DN = \framebox[1cm]{\phantom{X \(\times\) DS.


 (Theorem of internal division of chords)

\(\therefore\) \framebox[1cm]{\phantom{X \(\times\) DN = 15 \(\times\) 4

\(\therefore\) DN = \(\frac{\framebox[1cm]{\phantom{X}}}{8}\)

\(\therefore\) DN = \framebox[1cm]{\phantom{X

An observer at a distance of 10 m from tree looks at the top of the tree, the angle of elevation is 60\(^\circ\). To find the height of tree complete the activity. (\(\sqrt{3} = 1.73\))



Activity :


In the figure given above, AB = h = height of tree, BC = 10 m, distance of the observer from the tree.


Angle of elevation (\(\theta\)) = \(\angle\)BCA = 60\(^\circ\)


tan \(\theta\) = \(\frac{\framebox[1cm]{\phantom{X}}}{BC}\) \dots \dots \dots (I)


tan 60\(^\circ\) = \framebox[1cm]{\phantom{X \dots \dots \dots (II)

\(\frac{AB}{BC} = \sqrt{3}\) \dots \dots (From (I) and (II))


AB = BC \(\times\) \(\sqrt{3}\) = 10\(\sqrt{3}\)


AB = 10 \(\times\) 1.73 = \framebox[1cm]{\phantom{X

\(\therefore\) height of the tree is \framebox[1cm]{\phantom{X m.

Solve the following sub-questions (any four):

(1) In the following figure, XY \(||\) seg AC. If 2AX = 3BX and XY = 9. Complete the activity to find the value of AC.





Activity:


2AX = 3BX (Given)

\(\therefore \frac{AX}{BX} = \frac{3}{\framebox[1cm]{\phantom{X}}}\)

\(\frac{AX + BX}{BX} = \frac{3+2}{2}\) (by componendo)

\(\frac{BA}{BX} = \frac{5}{2}\) \dots \dots(I)


Now \(\triangle\) BCA \(\sim\) \(\triangle\) BYX (\framebox[1cm]{\phantom{X test of similarity)

\(\therefore \frac{BA}{BX} = \frac{AC}{XY}\) (corresponding sides of similar triangles)

\(\frac{5}{2} = \frac{AC}{9}\) from (I)

\(\therefore\) AC = \framebox[1cm]{\phantom{X

Complete the following activity to prove that the sum of squares of diagonals of a rhombus is equal to the sum of the squares of the sides.




Given: PQRS is a rhombus. Diagonals PR and SQ intersect each other at point T.


To prove: PS\(^2\) + SR\(^2\) + QR\(^2\) + PQ\(^2\) = PR\(^2\) + QS\(^2\)


Activity: Diagonals of a rhombus bisect each other.


In \(\triangle\)PQS, PT is the median and in \(\triangle\)QRS, RT is the median.

\(\therefore\) by Apollonius theorem,


PQ\(^2\) + PS\(^2\) = \framebox[1.5cm]{\phantom{X + 2QT\(^2\) \dots \dots(I)


QR\(^2\) + SR\(^2\) = \framebox[1.5cm]{\phantom{X + 2QT\(^2\) \dots \dots(II)


adding (I) and (II),


PQ\(^2\) + PS\(^2\) + QR\(^2\) + SR\(^2\) = 2(PT\(^2\) + \framebox[1.5cm]{\phantom{X) + 4QT\(^2\)


= 2(PT\(^2\) + \framebox[1.5cm]{\phantom{X) + 4QT\(^2\) (RT = PT)


= 4PT\(^2\) + 4QT\(^2\)


= (\framebox[1.5cm]{\phantom{X)\(^2\) + (2QT)\(^2\)

\(\therefore\) PQ\(^2\) + PS\(^2\) + QR\(^2\) + SR\(^2\) = PR\(^2\) + \framebox[1.5cm]{\phantom{X
