☬ Triangle ☬

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any threepoints, when non-collinear, determine a uniquetriangle and simultaneously, a unique plane.

formula for triangle

:-

area of a triangle =1/2×b×h

perimeter of a triangle=a+b+c or sum of three sides

solution ⤵️

in this case three sides of a triangle are respectively 3 cm,4cm and 5cm

perimeter of the triangle =3+4+5=12cm
