If it's a triangle then: 180-sum of known angles = unknown angle
Angles were known before trigonometry. Trigonometry was the study of angles and their relationship to shapes.
Right angles. Also known as 90 degree angles.
Sum of interior angles of an octagon= 1080˚

Start by studying something that you think you understand. That process should be an effective guide. In general, work from the known to the unknown; and from the concrete to the abstract.
It would depend on what you were studying for. If you have a general knowledge of the subject you are pursuing, it is best to study the materials that are known to be associated with it.
Right angles. Also known as 90 degree angles.
The scientific study of candles is known as "chirology."
They are known as complementary angles.
Sum of interior angles of an octagon= 1080˚
Angles combining to equal 90 degrees are known as complementary angles.
two 90 degree angles or also known as supplementary angles
An owl's favorite subject is typically about nature and animals, as they are natural hunters and predators. They are also known to be knowledgeable about their environment and have keen observational skills, making them great at studying their surroundings.
180 degreesAlso known as a straight angle.
