Is supplementary to an angle measuring between 1 and 89 degrees if the sum of the angles is 180 degrees.
Complementary angles are two angles whose measures add up to 90 degrees. For example, if one angle measures 30 degrees, its complementary angle would measure 60 degrees. They are often used in various geometric problems and applications, particularly in trigonometry. Complementary angles can be adjacent, sharing a common vertex and side, or non-adjacent.
To estimate angle measures, one effective strategy is to use the concept of complementary and supplementary angles. Complementary angles add up to 90 degrees, while supplementary angles sum to 180 degrees. By identifying known angles and applying these relationships, you can calculate unknown angles. Additionally, using a protractor for visual estimation can provide a more precise measure.
