What is pi? I forgot.

3.14159265359 or for short, 3.14

Step-by-step explanation:

It is a number that never repeats the same sequence and consists of over one million numbers and still continuing. Scientists and mathmaticians work to find the end of this seemingly endless number.

It can be used to find information of a circle when placed in a mathmaticle formula.

This number also appears in other forms of mathmatics as well as physics.

These are my own words.

I hope this helps and have a great day!

i dont know

step-by-step explanation:

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
