$\Rightarrow$ Small triangles in given figure $=△ABJ,△BCD,△DEF,△FGH,△HIJ$

$\Rightarrow$ Number of smaller triangle $=5$

$\Rightarrow$ Large triangles in given figure $=△CFI,△ADG,△BEI,△JCG,△AEH$

$\Rightarrow$ Number of larger triangle $=5$

$\Rightarrow$ Total number of triangle in given figure $=5+5=10$
