Yes because the sum of its smaller sides is greater than its longest side
no because a triangle has 3 sides only
A triangle has 3 and an hexagon has 6 so 3+6 = 9 sides
A scalene triangle
An equilateral triangle
They can have irregular or regular sides and are classed as follows:- 1 Triangle has 3 sides 2 Quadrilateral has 4 sides 3 Pentagon has 5 sides 4 Hexagon has 6 sides 5 Septagon has 7 sides 6 Octagon has 8 sides 7 Nonagon has 9 sides 8 Decagon has 10 sides 9 Undecagon has 11 sides 10 Dodecagon has 10 sides
no because a triangle has 3 sides only
A nonagon has 9 sides and a triangle has 3. So there are (5*9)+(1*3) = 48 sides in 5 nonagons and 1 triangle.
A triangle has 3 and an hexagon has 6 so 3+6 = 9 sides
A scalene triangle
An equilateral triangle
It has: 12-3 = 9 more sides
They can have irregular or regular sides and are classed as follows:- 1 Triangle has 3 sides 2 Quadrilateral has 4 sides 3 Pentagon has 5 sides 4 Hexagon has 6 sides 5 Septagon has 7 sides 6 Octagon has 8 sides 7 Nonagon has 9 sides 8 Decagon has 10 sides 9 Undecagon has 11 sides 10 Dodecagon has 10 sides
3*3 = 9 cm
26 units.

A triangle can have only three sides. No triangle can have 9 sides!
If you mean vertices of (-2, 9) (7, -3) and (-2, -3) then it is a right angle triangle with an hypotenuse of 15 and sides of 9 and 12 that all add up to 36 which is the perimeter of the triangle.
