Question

1. which term describes two angles that sum up to 90 degrees?

supplementary angles
complementary angles
exterior angles
linear pair angles

Explanation:

• Supplementary angles sum to \(180^{\circ}\).
• Complementary angles sum to \(90^{\circ}\).
• Exterior angles are related to polygons (e.g., sum of exterior angles of a polygon is \(360^{\circ}\)).
• Linear pair angles are adjacent and supplementary (\(180^{\circ}\)).

Answer:

Complementary angles
