Answer 2

hey himanshu...............!

here is ur answer!:)

i)a triangle is a closed figure made up of three line segments.
ii)the sum of all the angles of a triangle is 180°.
iii)the triangles can be classified on the basis of -a)sides b)angles.

#triangles based on sides-a)equilateral triangle(three sides of equal length)
                                        b)isosceles triangle(two sides of  equal length)
                                        c)scalene triangle(three sides of different length)

#triangles based on angles-a)acute angled triangle(whose all angles are                                                                                          less than °90)
                                          b)right angled triangle(whose one angle is 90°)
                                                                                   
                                          c)obtuse angled triangle(whose one angle is                                                                                            greater than 90°)
iv)the sum of the length of any two sides of a triangle is greater than the third side.
v)the side opposite to the largest angle is the longest side and the side opposite to the smallest angle is the shortest side.
