Question 10
The number of triangles in the given figure is
a) 10
b) 12
c) 13
d) 14

Answer 1

By observing the figure,

The total number of triangles are

1. $\Delta ABD$

2. $\Delta ADC$

and similarly the rest of them, $\Delta BDF$,$\Delta CDF$,$\Delta CFG$,$\Delta BEF$,$\Delta ABF$,$\Delta ACF$,$\Delta AFE$,$\Delta AFG$, $\Delta ABC$, $\Delta AEG$, $\Delta BCF$.

So, there are total 13 triangles in the given figure.
