A triangle is a polygon with three edges and three vertices. In Euclidean geometry any three points, when non-collinear, determine a unique triangle. Two triangles will be said congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
These video lectures have been prepared exclusively for all English medium state board and central board class 9th students to have the understanding on triangles.
