Step 1:
I'll solve this problem step by step:

Step 2:
: Recall the definition of complementary angles

Complementary angles are two angles that, when added together, form a right angle (90 degrees).

Step 3:
: Identify the key characteristics

- The sum of complementary angles is always $$90^\circ
- Each angle can be any value between 0° and 90° - The two angles complement each other to create a right angle

Step 4:
: Provide the specific term

Final Answer

Key points: - The word "complementary" specifically describes angles that sum to 90° - Example: An angle of 30° and an angle of 60° are complementary angles because 30^\circ + 60^\circ = 90^\circ - This is different from supplementary angles, which sum to 180°
