Complementary Angles
Two angles whose measures sum to 90 degrees, often forming a corner or right angle together. Supplementary Angles
Two angles whose measures sum to 180 degrees, typically forming a straight line together. Right Triangle
A triangle containing one 90-degree angle, with the other two angles always complementary. Complement
The angle that, when added to a given angle, results in a total of 90 degrees. Supplement
The angle that, when added to a given angle, results in a total of 180 degrees. Linear Equation
An algebraic equation used to solve for unknown angle measures based on their relationships. Variable
A symbol, often x, representing an unknown angle measure in equations involving angles. Negative Angle
A concept arising when an angle's complement would require subtracting beyond zero, which is not valid in this context. Straight Angle
An angle measuring exactly 180 degrees, representing a straight line. Right Angle
An angle measuring exactly 90 degrees, often indicated by a small square in diagrams. Equation Setup
The process of forming an equation to represent the sum of angles, such as x + y = 90 or x + y = 180. Angle Measure
The degree value assigned to an angle, determining its size and relationship to other angles. Triangle
A polygon with three sides and three angles, whose interior angles always sum to 180 degrees. Mnemonic
A memory aid, such as 'complementary corners' and 'supplementary straight,' to recall angle relationships.
