Question 3
A) True or false: Most proofs in geometry are called direct proofs because theorems
and postulates are used to prove a statement using a direct approach. (1 point)
The statement is true.
The statement is false. Most proofs in geometry are called direct proofs because it is
assumed the given statement is false and end the proof with a contradiction.
The statement is false. All proofs in geometry are called direct proofs because theorems
and postulates are used to prove a statement in a using a direct approach.
The statement is false. Most proofs in geometry are called indirect proofs because
theorems and postulates are used to prove a statement in a using a direct approach.
