SSC Mathematics Note 14th Chapter Ratio, Similarity, and Symmetry

SSC Mathematics Note 14th Chapter Ratio, Similarity, and Symmetry. For comparing two quantities,   their ratios are to be considered.  Again,  for determining ratios, the two quantities are to be measured in the same units.  In algebra, we have discussed this in detail. A polygon is a closed figure made of several line segments. A polygon is said to be regular if all its sides are of equal length and all its angles are equal. The triangle is a polygon made up of the least number of line segments.

An equilateral triangle is a regular polygon of three sides. An equilateral triangle is regular because its sides, as well as angles, are equal. A square is the regular polygon of four sides. The sides of a square are equal and each of the angles is equal to one right angle. Similarly, in regular pentagons and hexagons, the sides are equal and the angles are equal as well.
