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 (BRC) 1+2= 03 (QDB) 1+2= 03 (QDR) 1+2= 03 (QEC) 1+2= 03 (QER) And, the other triangles are; BRQ, BRD, RCQ, RCE, DQE Therefore, the total number of triangles in the above figure are 03+03+03+03+03+03+05= 13 triangles. |
