Triangle is a closed figure having some of all angles= 180 degrees or pi radians or 200 grads.
remember, a triangle is having above properties when drawn on a euclidean plane, in non-euclidean planes sum may be more or less than 180 degrees.

Answer 3

welll a triangle is just a three dimention figure. a triange may be of any shape and size. all the three side of triangle are joind end to end. a triangle may be right angled triange or isoseles triangle or may be equilateral triangle.

In right angled triangle the hypotenuse is greater than other two side.and the angle between them is 90

In isosceles triangle two sides of trialnge are equal

in equilateral triangle all the sides of the triangle are equal.
