Why is the square root of 36 equal to 6?

because that is what sqrt are

Step-by-step explanation:

A square root of a number is a value that, when multiplied by itself, gives the number. Example: 6 × 6 = 36, so a square root of 36 is 6 ... The symbol is √ which always means the positive square root.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
