It is the sum of the lengths of its sides.
When one of the numbers is greater or equal to the sum of the other two, then you can't have a triangle with those lengths. there are isosceles and equilateral triangles equilateral - all 3 sides and angles are the same isosceles - 2 sides are the same but the third is diffrent
is the sum of the lengths of the three sides.
The perimeter of any triangle is the sum of its 3 sides.
The perimeter formula of a triangle is the sum of the lengths of all three sides. Mathematically, it can be expressed as P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the three sides of the triangle.
It is the sum of the lengths of its sides.
I don't see any isosceles triangle below.In general, the perimeter is the sum of the lengths of all sides. Note that in an isosceles triangle, two of the three sides have the same length.

A triangle has no sum. There can be a sum of the measures of two or more angles, or the lengths of two or more sides, for example.
A perimeter of a triangle is the sum of all three lengths on the sides.
Yes. If the sum of the length of the two smaller sides are greater than the length of the larger side and none of the lengths of any of the sides equals 0, then it is a triangle. It is not, however, an equilateral triangle or right triangle (that would be 5, 4, 3), though it is an isosceles triangle.
Depends from the given information. For example, if it is given the measure of the angle base θ, and the length of the base b, the sum of the sides a of the isosceles triangle equals to 2a = b/cos θ If it is given the measure of the angle base θ, and the length of the height h, the sum of the sides a of the isosceles triangle equals to 2a = 2h/sin θ If it is given the measure of the vertex angle θ, and the length of the base b, the sum of the sides a of the isosceles triangle equals to 2a = b/sin θ/2 If it is given the measure of the vertex angle θ, and the length of the height h, the sum of the sides a of the isosceles triangle equals to 2a = 2h/cos θ/2 If it is given the length measures of the base b and the height h, the sum of the sides a of the isosceles triangle equals to 2a = √(h4 + b2) (from the Pythagorean theorem)
The perimeter of any triangle is the sum of its 3 sides
you add up the measures of the sides Perimeter=a+b+cAdd up the three sides together
