Subject :IMO Class : Class 5
In the given figure, which line is perpendicular to AB?
A CD
B EF
C GH
D IJ
it, can be line segment IJ
Ans 1:
Class : Class 8
B is the correct answer guys, look at the blocks carefully.
Ans 2:
Class : Class 8
Answer is C
Ans 3:
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.

Ans is C..... Olympiad Trainer please give master answer or solution.
Ans 18:
Class : Class 6
How is the answer B?
Ans 19:
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
