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

Activity:

r = 10 cm, θ = 90°, π = 3.14

A(P − AXB) = `θ/360 xx square`

= `square/360 xx 3.14 xx 10^2` 

= `1/4 xx square`

A(P − AXB) = `square` 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:

∴ MD × DN = `square` × DS   ...(Theorem of internal division of chords)

∴ `square` × DN = 15 × 4

∴ DN = `square/8`

∴ DN = `square`

An observer at a distance of 10 m from a tree looks at the top of the tree; the angle of elevation is 60°. To find the height of the tree, complete the activity. `(sqrt3 = 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 (θ) = ∠BCA = 60°

tan θ = `square/("BC")`  ...(I)

tan 60° = `square`  ...(II)

`("AB")/("BC") = sqrt3`  ...(From (I) and (II))

AB = BC × `sqrt3` = `10sqrt3`

AB = 10 × 1.73 = `square`

∴ Height of the tree is `square` m.

In the given fig, XY || seg AC. If 2AX = 3BX and XY = 9. Complete the activity to find the value of AC. 

Activity:

2AX = 3BX  ...(Given)

∴ `"AX"/"BX" = 3/square`

`("AX" +"BX")/"BX" = (3 + 2)/2`  ...(by componendo)

`square/"BX" = 5/2` ...(I)

Now ΔBCA ~ ΔBYX  ...`(square" test of similarity")`

∴ `"BA"/"BX" = "AC"/"XY"` ...(Corresponding sides of similar triangles)

∴ `square/square = "AC"/9` ...[From(I)]

∴ AC = `square`

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:

`square` PQRS is a rhombus. Diagonals PR and SQ intersect each other at point Т.

To prove: PS2 + SR2 + QR2 + PQ2 = PR2 + QS2

Activity:

Diagonals of a rhombus bisect each other.

In ΔPQS, PT is the median, and in ΔQRS, RT is the median.

∴ By Apollonius theorem,

PQ2 + PS2 = `square` + 2QT2  ...(I)

QR2 + SR2 = `square` + 2QT2 ...(II)

Adding (I) and (II),

PQ2 + PS2 + QR2 + SR2 = 2(PT2 + `square`) + 4QT2

= 2(PT2 + `square`) + 4QT2  ...(RT = PT)

= 4PT2 + 4QT2

= (`square`)2 + (2QT)2

∴ PQ2 + PS2 + QR2 + SR2 = PR2 + `square`
