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

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

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.

D cannot be the answer at all.

But what about the curved arrow

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

C

i also got it wrong

Ans 18:

Class : Class 5
How

Ans 19:

Class : Class 9
All figures have perpendicular lines

Ans 20:

Class : Class 5

Ans 21:

Class : Class 6
It is c

Ans 22:

Class : Class 8
All 4 figure has perpendicular line along perimeter

Ans 23:

Class : Class 5
'c' = correct

Ans 24:

Class : Class 6
it is d

Class : Class 7
CONFUSING QUESTION

Ans 26:

Class : Class 5
The answer should be C because in the first figure there are prependicular lines in the bottom in figure 2 there are prependicular lines all four sides near the arrows and in figure 3 there are prependicular lines at the bottom while there are no prependicular lines in figure 4 as they are all acute and obtuse angles so, the answer should be C not D.

Ans 27:

Class : Class 6
how

Ans 28:

Class : Class 8

Ans 29:

Class : Class 5
A perpendicular line is 90 degrees, last one doesn't count as 90 degrees, so C
