Class : Class 5
It is B since GH is not perpendicular by the smallest of angles. EF is perpendicular since if you look at the triangles or 5-sided shapes that are made when lines AB and EF come through a square with an angle not equal to 45 degrees, the sizes are the same. This shows that AB and EF are a pair of perpendicular lines.

the answer is d as the line needs to be a proper slant and only i-j is properly slanted

B is the correct answer guys, look at the blocks carefully.

Class : Class 6
The answer is C] GH Because if we count the blocks in AB then, it's4 If we count the blocks in GH then, it's4 THIS S MY FORMULAE

D is the answer to this question because all the lines are perpendicular and in the 3rd one the bottom lines are perpendicular

## Ans 3:

All 4 figure has perpendicular line along perimeter

Something is wrong here. We have to confirm about it.

Class : Class 5
it is d

Class : Class 6

Class : Class 6
It is c

i also got it wrong

Class : Class 5

## Ans 19:

Class : Class 5
Angles consideration is confusing ....sometime inner and sometime outer angle is consider ....actually SINGLE LINE FIGURE SHOULD BE GIVEN

Class : Class 8

Class : Class 6
how

## Ans 22:

Class : Class 6
All figures have perpendicular lines

## Ans 23:

Class : Class 7
It should be C as it is written that we have to find the perpendicular line for each figure, so there are three figures with perpendicular line but if we consider how many perpendicular lines are there in this picture then it should be 4. This answer is absolutely wrong.

Class : Class 5
yes

There are four equations P Q R=75; Q R S=90; P R S=100; Q S P=80Add them up all. You will get 3P 3Q 3R 3S=345. This means P Q R S=115We can replace the value of P Q R=75 in the above to get the value of S which would be 40. From the second equation, we can get the total value of Q R 40=90 as 50
