Study Notes
Key Geometry Concepts
-
Distance Formula: Calculates the distance between two points ((x1, y1)) and ((x2, y2)) using the formula ( \sqrt{(x2−x1)^2+(y2−y1)^2} ).
-
Midpoint Formula: Determines the midpoint between two endpoints ((x1, y1)) and ((x2, y2)) with the formula ( \left(\frac{x1+x2}{2}, \frac{y1+y2}{2}\right) ).
-
Angle Bisector: A line or ray that splits an angle into two equal angles, ensuring congruence.
-
Collinear Points: A collection of points that all lie on the same straight line.
-
Complementary Angles: Two angles whose measures add up to 90 degrees.
-
Congruent Angles: Angles that have the same measure, indicating equality.
-
Coplanar Points: Points that all exist within the same geometric plane.
-
Line Definition: A straight one-dimensional figure that extends infinitely in both directions, containing an infinite number of points and having no thickness.
-
Midpoint: The exact center point between two endpoints of a line segment.
-
Perpendicular Lines: Two lines that intersect to form four right angles (90 degrees each).
-
Plane: A flat two-dimensional surface with no thickness that extends infinitely; defined by at least three non-collinear points.
-
Point: An exact location in space, represented by a dot and labeled with a capital letter, having no dimensions.
-
Segment Bisector: A specific line or segment that divides another segment into two equal parts.
-
Supplementary Angles: Two angles that together total 180 degrees.
-
Vertex: The point where two lines or rays meet to form an angle.
-
Vertical Angles: Angles that are opposite each other when two lines intersect, known for being congruent (equal in measure).
