What is an undefined term of geometry

coplaner

True or false In the body of an indirect proof you must show that the assumption leads to a contradiction

True
It is true that the body of an indirect proof you must show that the assumption leads to a contradiction. In math a proof is a deductive argument for a mathematical statement.

True or false A corollary is a statement that can be easily proved using a theorem

For Apex the answer is “True“.

A corollary is a statement that can easily be proved using a theorem

A corollary is a statement that can easily be proved using a theorem.

In the body of an indirect proof you must show that the assumption leads to a contradiction

true

Which are accepted without proof in a logical system Postulates Axioms Theorems or Corollaries

Postulates and axioms are accepted without proof in a logical system. Theorems and corollaries require proof in a logical system.

If four points are collinear they are also coplaner

I dont think that "If four points are collinear they are also coplaner," is the same thing as "If four points are coplaner they are also collinear,". The definition of collinear is at least three points on the same line. To define a plane is to have threenoncollinear points.

Is it true that a theorem is a statement that can be easily proved using a corollary

false

Is it false that and indirect proof assumes the opposite of what needs to be proved and then arrives at a contradiction

true

What best describes the meaning of the term theorem

A conclusion provided by deductive reasoning

Which term best describes a proof in which you assume the opposite of what you want to prove

The term that best describes a proof in which you assume the opposite of what you want to prove is 'indirect proof'.

True of false in a two-column proof the left column states your reasons

In a two-column proof, it is true that the left column states your reasons.

A. Flowchart proof

True or false in a two column proof the right column states your reasons.

True

Postulates are statements the require proof true or false

False

A logical argument that is presented in graphical form using boxes and arrows is called a what

Flowchart proof

Which counterexample shows that the conjecture Every four-sided figure is a parallelogram is false

Every four sided figure is a quadrilateral which includes a parallelogram.
