- Definition of Vertical Angles states that angles directly opposite of each other are the same measurement. In this case, the pair of opposite angles are: ∠DCH & ∠FCB.
m∠ABE = 84° (Corresponding angles)
- Definition of Corresponding angles states that matching corners of parallel lines cut across by a Transversal are congruent. In this case, ∠FCB is corresponding to ∠ABE. m∠FCB = 84°, ∴ m∠ABE = 84°
The option which best describes the meaning of the term theorem is <span><u>B. A conclusion proved by deductive reasoning. </u>A refers to hypothesis, C to an axiom, and D to a definition. <u> </u></span>
