Two angles are complementary angles if they add up to _____ degrees. They do not have to be next to each other. When two lines intersect, four angles are created to having a point of intersection at the _____. The angles that are _____ from each other are considered to be vertical angles. They are also _____.
Complementary angles are two angles whose sum is 90°. So, the complement of 50° is (90 – 50), that is 40°. The complement of 40° is just the reverse, which is 50°. Supplementary angles are two angles whose sum is 180°. It can also be called linear pair of angles. The sum of a pair of linear angles is always 180°.

The sum of the measure of the angles of a triangle is 180o Corollary The acute angles of a right triangle are complementary. Exterior angle theorem An exterior angle of a triangle is equal in measure to the sum of the measures of its two remote interior angles. Triangle Proportionality Theorem
Examples: 1. Find the measure of the complement and supplement of a 43 angle. 2. ⊥Given: ⃗⃗⃗⃗⃗ ⃗⃗⃗⃗⃗ , m 2 is three greater than twice m 1. Find the measure of each angle. 3. The measure of the supplement of an angle is 60 less than 3 times the measure of the complement of the angle.
In geometry, complementary angles are defined as two angles whose sum is 90 degrees. Two complementary angles when put together form a right angle. Learn the differences between complementary and supplementary angles.
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.
