Question

two angles added together to produce 90 degrees (with options: complementary, right, vertical, supplementary)

Explanation:

To solve this, we recall the definitions of the terms:

• Complementary angles: Two angles whose sum is \(90^\circ\).
• Right angle: An angle of \(90^\circ\) (not a pair of angles).
• Vertical angles: Angles opposite each other when two lines intersect (their sum isn't necessarily \(90^\circ\)).
• Supplementary angles: Two angles whose sum is \(180^\circ\).

Since the question is about two angles adding to \(90^\circ\), the correct term is Complementary.

Answer:

A. Complementary
