Given that:
Line l is perpendicular to line m.
a) We can clearly see from the above diagram that CE = 5-3= 2 units
Also, EG = 7-5 = 2 units
∴ CE = EG = 2 units
b)As we have seen above CE = EG
So, E is the mid-point of line CG.
∴ Line PE bisects CG.
c) We can see from the above figure that
BE = 5-2 = 5 units
HE = 8-5 = 3 units
∴ E is the mid-point of the line BH.
Also given that line m is perpendicular to the line l.
∴ PE is the perpendicular bisector of the line segment BH.
Also, we have seen above that PE is also the perpendicular bisector of line segment CG.
∴ The required line segments are BH and CG.
Answer: Option C. -> 300m
:
C
If you cover 360∘ of the track , the length covered = 400m
So,
For 180∘, the length covered will be
=12(400m)=200m
For 90∘, the length covered will be
=12(200m)=100m
∴ For 270∘, the length covered = length covered for 180∘+ length covered for 90∘
=200m+100m=300m

Answer: Option C. -> Using a divider and a ruler
:
C
We can't measure length using a compass. By guessing, the length measured will be lessaccurate. By using ruler we can measure, but the accuracy decreases if the angle at which it isviewedis not appropriate. By using the divider and a ruler, we can measure the length moreaccurately.

Answer: Option D. -> 1 and 3
:
D
In a regular polygon, all the angles should be equal in measureand all the sides should be equal in length. This is true only for figures 1 and 3.

Answer: Option A. -> Point C lies between A and B
:
A
We can see that AC + CB = 4 cm + 9 cm = 13 cm = AB. So, C lies between A and B.
:
A
We can see that AC + CB = 4 cm + 9 cm = 13 cm = AB. So, C lies between A and B.

Given that:
ABCD is a rectangle.
E and F are the mid-points of the lines ACand BDrespectively.
∴AE=BF=EC=FD
Also, AH=HB=CG=GD [ H is mid point of AB , G is midpoint of CD ]
∠A,∠B,∠C and∠D are right angles.
The four sides of rectangle formed i.e. EHFG will have equal dimensions.
∴The length of all their diagonals will also be same.
EH=HF=FG=EG
All sides of the quadrilateral are equal.
So either it will be a Rhombus or a Square.
But for both of these quadrilaterals, the diagonals intersect at a right angle.
The angle formed between the diagonals is a right angle.
