Study Notes
Properties of a Line
- A line extends infinitely in two directions and has no thickness or width.
- A line can be named using two points on the line, with a double arrow above the letters.
- A line segment is a part of a line with two distinct endpoints.
Types of Angles
- Acute angles are less than 90 degrees.
- Right angles are exactly 90 degrees.
- Obtuse angles are greater than 90 degrees but less than 180 degrees.
- Straight angles are exactly 180 degrees.
- Reflex angles are greater than 180 degrees but less than 360 degrees.
Angles in a Triangle
- The sum of the angles in a triangle is always 180 degrees.
- This is true for all types of triangles, including equilateral, isosceles, and scalene.
