Final answer:
The right angle definition supports the statement that ±45 m < ∠AOW = 90, stating that a right angle measures exactly 90 degrees.
Step-by-step explanation:
The right angle definition supports the statement that ±45 m < ∠AOW = 90, stating that a right angle measures exactly 90 degrees. The evidence in the proof that supports the statement that 45 m < ∠AOW = 90 is the right angle definition. The right angle definition states that a right angle is an angle that measures exactly 90 degrees.
The mention of the Pythagorean theorem in the question, which defines the relationship between the sides of a right triangle (a, b, and c where c is the hypotenuse), supports the existence of a right angle in a triangle but does not specifically claim that ∠AOW is a right angle. Thus, the correct choice that directly supports the statement in question is the right angle definition, which tells us that ∠AOW is a 90-degree angle if it is defined as a right angle.
