Below is the justification for the formula for area of a circle. Which word, when placed in the blank, best completes this argument?
.
.
The circumference of a circle is given by the formula c = 25r where r is the
radius.
If the circle is divided into equally sized sectors, the sectors can be
rearranged to form a shape that approximates a parallelogram.
The base of the parallelogram is half the circumference, or er, and the
height is
Because the area of a parallelogram is equal to the product of the base
and the height, the area is ?
Therefore, the area of a circle is given by the formula sr?.

im not sure

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
