How many triangles are present in the given figure?

Solution

The different triangles in the figure ACG are CBD, BED, DEF, DFG, ABE, AFE, ABD, AFD, ACD, AGD, ACG

$$\Rightarrow$$ Number of triangles in figure ACG = 11

The figure HIJ is similar to figure ACG.

$$\Rightarrow$$ Number of triangles in figure HIJ = Number of triangles in figure ACG = 11

$$\therefore\ $$Number of triangles in the given figure = 11 + 11 = 22

Hence, the correct answer is Option A
