Study Notes
Triangle Angles
- The sum of all interior angles in a triangle is always 180 degrees.
Types of Angles
- Acute angles have a measure between 0 and 90 degrees, representing sharp corners.
Straight Angle
- A straight angle measures exactly 180 degrees, forming a straight line.
Complementary Angles
- Two angles that add up to 90 degrees are known as complementary angles, often used in geometry.
Halfway Angle
- An angle that is halfway between 0 and 180 degrees measures 90 degrees, which is a right angle.
Vertically Opposite Angles
- Angles that are opposite each other when two lines intersect are called vertically opposite angles, and they are always equal in measure.
