A compound angle is formed when two or more angles are joined together at a common vertex. The combined angle measure is equal to the sum of the individual angles.
Multiple angles are formed when two or more angles are extended beyond a common vertex, forming a larger angle. The combined angle measure is equal to the sum of the individual angles, regardless of their position.
Examples:
Compound angle: The angle formed by two rays intersecting at a point is equal to the sum of the angles formed by each individual ray. For example, if angle A = 30° and angle B = 45°, then angle A + angle B = 75°.
Multiple angles: The angle formed by two rays extending beyond a point is equal to the sum of the angles formed by each individual ray. For example, if angle A = 60° and angle B = 30°, then angle A + angle B = 90°.
Examples of compound angles: A triangle with angles A, B, and C, where angle A + angle B + angle C = 180°, is a compound angle.
Additional Notes:
All angles are measured in degrees.
The sum of all angles in a triangle is always 180°.
The sum of the angles in a quadrilateral is equal to 360°
