Answer 1

$\setlength{\unitlength}{1 cm}\begin{picture}(0,0)\thicklines\qbezier(1, 0)(1,0)(3,3)\qbezier(5,0)(5,0)(3,3)\qbezier(5,0)(1,0)(1,0)\put(2.85,3.2){ \bf A }\put(0.5,-0.3){ \bf C }\put(5.2,-0.3){ \bf B }\end{picture}$

$\mathrm\blue{Triangle}$

A triangle is a polygon with three vertices and three angles .

In Fig. , triangle ABC is there , where

A , B and C are the vertices .

$\mathrm{\angle{A} ~,~\angle{B}~and~\angle{C}~are~the~angles}$

$\mathrm\blue{Properties}$

The sum of the three interior angels of triangle is always 180°.

The sum of two sides of triangle is always greater than the third side .

Answer 2

Answer:

In geometry, a triangle is a closed, two dimensional shape with three straight sides.

A triangle is also a polygon.

Properties of a Triangle:

A triangle has three sides, three vertices and three angles.

The sum of the three interior angles of a triangle is always 180°.

The sum of the length of two sides of a triangle is always greater than the length of the third side.

A triangle with vertices P, Q, and R is denoted as △PQR.

The area of a triangle is equal to half of the product of its base .
