How many triangles are there in the given figure? |
12 10 11 9 |
11 |
The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03 (LBM) And, the other triangles are; ACB, NPO, BCD, CQP, QNR, NRB, CRO, NQB Therefore, there are 03+07= 11 triangles in the above figure |
