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

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.

'c' = correct

Ans 20:

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.

All figures have perpendicular lines

All 4 figure has perpendicular line along perimeter

It is c

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

Ans 28:

Class : Class 9
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.
