the angle relationship between the angles that you are working with. Are they supplementary (sum to 180 0 ) OR complementary(sum to 90 )? Are they congruent to each other? vertical, alternate interior, alternate exterior , or corresponding angles.
Problems on complementary and supplementary angles are most easy to solve if you just remember the numbers 90 and 180. With the definitions given below, you will know how these numbers have been used in angles. You have ample problems to identify and calculate the missing measure of angles.
The complementary angle theorem states that if two angles are complementary to the same angle, then they are congruent. But how did this theorem exist? Let’s find out by proving.
Complementary angles are a pair of angles that, when added together, equal 90°. In simpler terms, if you have ∠1 and ∠2, and their measures sum up to 90°, then ∠1 and ∠2 are considered complementary. We refer to ∠1 and ∠2 as each other's complements based on this relationship.
4) The complementary angle of 54° is 36° 5) The complementary angle of 85° is 5° 6) The complementary angle of 84° is 6° 7) The complementary angle of 44° is 46° 8) The complementary angle of 60° is 30° 9) The complementary angle of 34° is 56° 10) The complementary angle of 63° is 27° 11) The supplementary angle of 121° is 59°
The complementary angle theorem states, "If two angles are complementary to the same angle, then they are congruent to each other". Proof of Complementary Angles Theorem: We know that complementary angles exist in pairs and sum up to 90 degrees. Consider the following figure and prove the complementary angle theorem.
