Test: Geometry- 2 - Question 4

PQRS is a Trapezzium, in which PQ is Parralel to RS, and PQ = 3 (RS) . The diagnol of the Trapezzium intersect each other at X, then the ratio of,  ar ( ∆ PXQ)  : ar ( ∆ RXS)  is?

Detailed Solution for Test: Geometry- 2 - Question 4

In ∆ PXQ and ∆ RXS

=> angle P = angle R

    angle Q  =  angle S 

:- ∆ PXQ  ~ ∆ RXS  ( AA similarity rule)  

ar ( ∆ PXQ) /  ar ( ∆ RXS) = ( PQ / RS) ^ 2 

 =  ( 3 / 1 ) ^ 2

=     9 / 1 

Therefore,  ar ( ∆ PXQ) :  ar          ( ∆ RXS) 

=   9:1

Test: Geometry- 2 - Question 5

Detailed Solution for Test: Geometry- 2 - Question 9

Test: Geometry- 2 - Question 10

What is the area of the triangle in which two of its medians 9 cm and 12 cm long intersect at the right angles?

Detailed Solution for Test: Geometry- 2 - Question 10

Test: Geometry- 2 - Question 11

Four horses are tethered at four comers of a square plot of side 14 m so that the adjacent horses can just reach one another. There is a small circular pond of area 20 m2 at the centre. Find the ungrazed area.

Detailed Solution for Test: Geometry- 2 - Question 11

Total area of plot = 14 * 14 = 196m2
Horses can graze in quarter circle of radius = 7m
Grazed area = 4 * (pie r2)/4 = 154 m2
Area of plot when horses cannot reach = (196 - 154) = 42m2
Ungrazed area = 42 - 20 = 22m2

Test: Geometry- 2 - Question 12

Two sides of a triangle are 4 and 5. Then, for the area of the triangle, which one of the following bounds is the sharpest?

Detailed Solution for Test: Geometry- 2 - Question 12

Let AB = 4 and BC = 5 and AB is perpendicular to BC

then Area = 1/2 AB . AC = 1/2 . 4.5 = 10 

Test: Geometry- 2 - Question 13

A rectangle with the largest possible area is drawn inside a semicircle of radius 2 cm. Then, the ratio of the lengths of the largest to the smallest side of this rectangle is?

Detailed Solution for Test: Geometry- 2 - Question 13


Let the longer side of the rectangle is 2a and the shorter side is b as shown in the figure.

Using pythagoras theorem, we get
a2 + b2 = 22 = 4   ...(1)

Also, AM ≥ GM

⇒ a2 + b2 ≥ 2ab

⇒ 4 ≥ 2ab

⇒ 2 ≥ ab

∴ Highest value of ab = 2, when a = b.

⇒ Ratio of longer side to shorter side = 2a : b = 2 : 1.

Hence, option (a).

Test: Geometry- 2 - Question 14

The lengths of all four sides of a quadrilateral are integer valued. If three of its sides are of length 1 cm, 2 cm and 4 cm, then the total number of possible lengths of the fourth side is

Detailed Solution for Test: Geometry- 2 - Question 14

In a quadrilateral, the longest side is less than the sum of other three sides and greater than the least of the difference of any 2 of the other three sides.

Let the fourthe sides of the quadrilateral be x.

⇒ 2 - 1 < x < 1 + 2 + 4
⇒ 1 < x < 7
∴ x can be 2, 3, 4, 5 or 6

Hence, x can take 5 integral values.

Hence, option (a).

Test: Geometry- 2 - Question 15

Suppose the length of each side of a regular hexagon ABCDEF is 2 cm. If T is the mid point of CD, then the length of AT, in cm, is

Detailed Solution for Test: Geometry- 2 - Question 15

Side of the regular hexagon = 2 cm.
Consider the figure below.

Consider the isosceles ∆ATF

TU is the altitude from T to AF. 
We know, in a regular hexagon the distance between any two parallel sides = √3 × side.
∴ TU = √3 × 2 = 2√3 cm.

Since ATF is an isosceles triangle, U will be the mid-point of AF
∴ AU = 1 cm.

In ∆ATU
AT2 = TU2 + AU2
⇒ AT2 = (2√3)2 + 12
⇒ AT2 = 13
⇒ AT = √13

Hence, option (c).
