Which of the following statements is true for ∠a and ∠b in the diagram? Question 4 options:

A)

m∠a + m∠b = 180°

B)

m∠a = m∠b

C)

m∠a + m∠b = 90°

D)

m∠a – m∠b = 90°

B. m∠a = m∠b

Step-by-step explanation:

This statement is true due to the Alternate Interior Angle Theorem, which states: If ∠a = x, then ∠b = x, meaning that if a equals a certain angle measure, then the alternate interior angle, or the angle opposite a, must also be the same measure.
