If ab and ac are each as long as bc then the triangle is, in fact, equilateral, not just isosceles. Therefore, each side is 20/3 cm = 6.66... recurring cm.

The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.
It can be. If two of the sides of a right triangle are the same length then it is an isosceles triangle
All 3 sides of an equilateral triangle are equal in length Only 2 sides of an isosceles triangle are equal in length
If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
Perimeter of the isosceles triangle: 16.2+16.2+8.1 = 40.5 cm
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.

-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle.
Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.
That's not enough information to solve the problem.
Perimeter = 10 + 10 + 12 = 32 units. Area = 48 square units
An isosceles triangle has to have two sides of equal length. An isosceles triangle has to have two sides of equal length.
-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle. ----------------------------------- The perimeter is the sum of all three sides. Sometimes it is unnecessary to compute each side length; all we care about is the sum.

An isosceles right triangle will always have its shorter sides of the same length, and the hypotenuse will always be this length times sin(45o) or times the square root of 0.5.
