Find the number of triangles in the given figure. |
13 17 19 15 |
15 |
The logic followed here is; (let's keep in mind the base, means how many triangles are there in the base) 1+2= 03 (ABC) 1+2= 03 (LMN) 1+2= 03 (RCS) And, the other triangles are; PMR, QNS, LQB, LPA, LQC, LPC Therefore, there are 03+03+03+06= 15 triangles in the above figure. |
