Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio.
Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
<h3>What is a polygon and a triangle ?</h3>
A Polygon is a closed figure made up of line segments (not curves) in a two-dimensional plane. Polygon is the combination of two words, i.e. poly (means many) and gon (means sides). A minimum of three line segments is required to connect end to end, to make a closed figure.
Triangles, hexagons, pentagons, and quadrilaterals are all examples of polygons.
A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°.
Therefore;
Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio.
Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
