Count the number of parallelogram in the given figure.
Answer: Option
Explanation:
The figure may be labelled as shown.
The parallelograms composed of two components each are ADME, DFNM, EMOG, FHJN, MNKO, GOLI, HBJN, NJKO, OKLI, FHNM, MNOG, DFME, HJKN, NKLO, OLCI, FNOM, MOIG and DMGE. i.e. 18 in number.
The parallelograms composed of four components each are HOKB, NILJ, FGOH, HOLJ, NICK, FGIN, FMJB, DENH, MGKJ, MGCL, DEIO, FMLK, AENF, AGOD, DMJH, DOKF, EILM and EGKN i.e. 18 in number.
The parallelograms composed of six components each are AEJH, DAIL, DECL, DEJB, HILB and HICJ i.e. 6 in number.
The parallelograms composed of eight components each are FGKB, FGCK and AGKF i.e. 3 in number.
Total number of parallelograms in the figure = 18 + 18 + 6 + 3 = 45.

How many triangles are in this triangle? Can anybody help me?

To find the no of triangles in this kind of picture use this formula : [n (n + 2) (2n + 1)]/8. Where n is no of rows.

In this situation, we can give the number to each point of the triangle as.
If there is even number we can use the formula the total number of the triangle is: n (2n*2-n-2).
If there is add number we can use the formula the total number of the triangle is: (n*2-1) (2n-1) /8.
As this method here is the number is 5 so it adds number and uses the for fomula : (5*5-1) (5*2-1) /8.
=24*9/8.
=27.
