Study Notes
Triangle Geometry
- The sum of interior angles in any triangle always equals 180 degrees.
Circle Definition
- A circle is defined as the set of all points that are equidistant from a central point.
- This distance from the center is called the radius.
Distance Formula
- The distance between two points in a Cartesian plane (x, y) can be calculated using the distance formula: $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$.
Isosceles Triangle
- An isosceles triangle has two sides of equal length.
Slope of a Line
- A line that rises as it moves from left to right has a positive slope.
