Find the number of triangles in the given figure. |
29 31 27 33 |
31 |
The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03 (ABD) 1+2= 03 (CDB) And, the other triangles from 1st square are; ABC & ADC Now, we have 03+03+02= 08 triangles ---> Total number of squares= 03 So, 08x03= 24 triangles And, the other triangles from 2nd & 3rd squares are; CEH, ACE, BFG, DBF Now, we have 24+04= 28 triangles Plus, APQ, PQG, APG Therefore, the total number of triangles in the above figure are 28+03= 31 triangles.
