Find the number of triangles in the given figure.

Answer: Option

Explanation:

The figure may be labelled as shown.

The simplest triangles are IJO, BCJ, CDK, KQL, MLQ, GFM, GHN and NIO i.e. 8 in number.

The triangles composed of two components each are ABO, AHO, NIJ, IGP, ICP, DEQ, FEQ, KLM, LCP and LGP i.e.10 in number.

The triangles composed of four components each are HAB, DEF, LGI, GIC, ICL and GLC i.e. 6 in number.

Total number of triangles in the figure = 8 + 10 + 6 = 24.

@All.

The shortcut method is;

Total no.of nodes + 2(no.of inner nodes).

=14 + 2 (5),

=24.

It has 25 triangles.

Ans- middle square has =8 triangles by twice method( count all triangles and then last part *2) then you see three same types of triangles at first, second and at last which has 3 - 3 - 3 equal triangles =9, and at last small and simple triangles are 8 (at sides and middles). So that's all answer is 25.
