How many triangles are there in the given figures?

**(i) Solution**

A, B, C, D are four triangles.

Combining A & D, B & D and D & C do
not form any triangles.

Combining A, B & D; A, C & D and B, D &
C also do not form any triangles.

Combining A, B, C & D = 1 triangle

Total
number of triangles =
4
+
1
=
5

**(ii) Solution**

A, B, C, D, & E are five triangles.

No combination of these triangles taken 2 at a time,
form any triangle.

Only the combinations of A, F & C; A, F &
D; B, F & E; B, F & D and C, F & E form triangles when taken 3 triangles
at a time. Hence, the total number of triangles = 5 + 5 = 10.
