Which choice below is NOT a possible feature of a conjecture? It's a falsehood
It's a question
It's a declarative statement
It's the truth.

The correct option is;

It's a falsehood

Step-by-step explanation:

A conjecture is a form of declarative statement or proposal that is guessed as being correct or the truth based on the available evidence that contributes to the correctness of the statement but is yet have a disproof or proof

Therefore, a conjecture can be correctly the truth, a declarative statement based on observation or a question but not a falsehood because then it will not be based on any logical supporting evidence.

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
