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)

What is the perimeter of the isosceles triangle shown below If necessary round to the nearest hundredth.?
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.
What is the sum of an isosceles triangle that has two sides with lengths of 4 and x?

How much degrees are in a isoscelese triangle?
The angles inside any triangle sum to 180 degrees. Isosceles simply means two sides are the same length.
What is the 4 mistakes of this phrase The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side?
The Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. 1. squares, not square roots 2. right triangle, not isosceles 3. sides opposite the hypotenuse, not any two 4. What are the mistakes, not what is

What is the total angle measure of isosceles triangle?
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
What is the degrees of an isosceles triangle?
An isosceles triangle has 3 interior angles that add up to 180 degrees, and 2 of its angles are equal and two of its sides are equal.
What is perimetre of a triangle?

What is the angle sum of a obtuse isosceles triangle?
The angle sum of any triangle is 180 degrees. It does not matter whether it is equilateral, isosceles or scalene, nor whether it is acute angled, right angled or obtuse angled (or any permitted combination).
