How many triangles are there in the following figure?
Answer & explanation
Correct answer: option 3

The logic followed here is;
(let's keep in mind the base, means how many triangles are there in the base)
1+2= 03 (ABE)
1+2= 03 (HBE)
1+2= 03 (DHE)
1+2= 03 (DFC)
1+2= 03 (BCD)
1+2= 03 (CIJ)
And, the other triangles are;
BED, ABH, AHE, EHF, DHF, BED, ECD, BCE
Therefore, there are 03+03+03+03+03+03+08= 26 triangles in the above figure.
