A scalene triangle is a triangle in which there are no sides or angles with the same measures.

So?
A triangle with three sides is a polygon.
A right triangle is a triangle in which one of the three angles measures 90°. In other words, it is a triangle with two sides that are perpendicular to each other.
An Equilateral Triangle
state if the three numbers can be measures of the sides of a triangle. show your work 1- 15,12,9
A triangle, by definition, can have only three sides. So a four sided triangle simply cannot exist!A triangle, by definition, can have only three sides.

A scalene triangle is a triangle in which there are no sides or angles with the same measures.
perimeter
Any and every triangle has three sides and three angles; that is the defintion. The type of triangle cannot be determined without more information.
No it cannot. A triangle is by definition a three sided shape.
So?
A quadrilateral triangle is an oxymoron.A quadrilateral has four sides, a triangle has three so a quadrilateral triangle cannot exist. You could therefore say that it has zero sides.
you add up the measures of the sides Perimeter=a+b+cAdd up the three sides together
To find the perimeter of a triangle, add the three sides. Perimeter = 6in + 8in + 10in = 24in.
A triangle with three sides is a polygon.
