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

## Ans 23:

Class : Class 5

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

## Ans 24:

Class : Class 6

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.

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

## Ans 9:

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 11:

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

## 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.

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