Maths Mock Test- 5 - Question 1

The point A(3, 4) lies in

Detailed Solution for Maths Mock Test- 5 - Question 1

2. I Quadrant

Explanation:

The point A(3, 4) lies in the I Quadrant because:

  • In the I Quadrant, both the x-coordinate (abscissa) and the y-coordinate (ordinate) are positive.
  • Since 3 (x-coordinate) is positive and 4 (y-coordinate) is also positive, the point lies in the I Quadrant.

Maths Mock Test- 5 - Question 6

Two planes intersect each other to form a :

Detailed Solution for Maths Mock Test- 5 - Question 6
Two non-parallel planes in space form a line upon intersection, as long as each plane is unique. Three non-parallel planes intersect at a point. The best and simplest example is to fold a piece of paper. Since the folded paper now represents two distinct planes, the crease itself is the intersection point, forming a line.

Maths Mock Test- 5 - Question 10

The point (0, 9) lies

Maths Mock Test- 5 - Question 11

If APB and CQD are 2 parallel lines, then the bisectors of the angles APQ, BPQ, CQP and PQD form, square only if

Detailed Solution for Maths Mock Test- 5 - Question 11
Line APB is parallel to CQD
when we join PQ it will be transversal
then angleBPQ=angleCQP    (alternate angles)
angleAPQ=anglePQD   
when we will draw bisectors 
then the figure formed will have opposite angles equal
which means that it is a parallelogram

Maths Mock Test- 5 - Question 12

If bisectors of ∠A and ∠B of a quadrilateral ABCD intersect each other at P, of ∠B and ∠C at Q, of ∠C and ∠D at R and of ∠D and ∠A at S, then PQRS is a

Detailed Solution for Maths Mock Test- 5 - Question 12

To show: ∠PSR + ∠PQR = 180°
∠SPQ + ∠SRQ = 180°

In △DSA,

∠DAS + ∠ADS + ∠DSA = 180° (angle sum property)

+ ∠ SA = 180° (since RD and AP are bisectors of ∠D and ∠A)

∠DSA = 180°
∠PSR = 180°−

(∵ ∠DSA = ∠PSR are vertically opposite angles)

Similarly,

∠PQR = 180°− 


Adding (i) and (ii), we get, ∠PSR + ∠PQR = 180°
=360° − 1/2 ​× (∠A + ∠B + ∠C + ∠D)
 

=360°− 1/2​ × 360° = 180° ∴ ∠PSR + ∠PQR = 180°

In quadrilateral PQRS,

∠SPQ + ∠SRQ + ∠PSR + ∠PQR = 360°
=> ∠SPQ + ∠SRQ + 180° = 360°
=> ∠SPQ + ∠SRQ = 180°

Hence, showed that opposite angles of PQRS are supplementary.

Maths Mock Test- 5 - Question 23

Detailed Solution for Maths Mock Test- 5 - Question 23

ANSWER :- b

Solution :- (0.75 * 0.75 * 0.75 + 0.25 * 0.25 * 0.25)/(0.75 * 0.75 - 0.75 * 0.25 + 0.25 * 0.25)

= (0.421875 + 0.015625)/(0.5625 - 0.1875 + 0.0625)

= (0.4375)/(0.4375)

= 1

Maths Mock Test- 5 - Question 26

If the altitudes from two vertices of a triangle to the opposite sides are equal, then the triangles is

Detailed Solution for Maths Mock Test- 5 - Question 26

Given:

BE = CD

Concept Used:

When 2 sides of a triangle are equal, then it is isosceles.

When 2 angles and 1 side of 2 triangles is equal, then both the triangles are similar.

Calculations:

In △ABE and △ACD,

BE = CD (Given)

∠BEA = ∠CDA (90° each)

∠BAE = ∠CAD (Common Angle)

∠ABE = ∠ACE (By Sum angle property)

⇒ △ABE is similar to △ACD

⇒ AB = AC

∴ If the altitudes from two vertices of a triangle to the opposite sides are equal, then the triangle is isosceles.

Maths Mock Test- 5 - Question 27

In △AOC and △XYZ, ∠A =∠X, AO = YZ, AC = XY, then by which congruence rule △AOC ≅ △XYZ

Detailed Solution for Maths Mock Test- 5 - Question 27

To determine the congruence rule for ΔAOC and ΔXYZ:


  • Given: ∠A = ∠X

  • AO = YZ (one pair of corresponding sides)

  • AC = XY (another pair of corresponding sides)

  • Two pairs of sides and the included angle are equal

  •  

Therefore, by the SAS (Side-Angle-Side) congruence rule, ΔAOC ≅ ΔXYZ.
