Study Notes
Basic Geometric Terms
- Straight Angle: Measures exactly 180 degrees.
- Adjacent Angles: Share a common side and vertex, located next to each other.
- Horizontal Line: Extends side to side, parallel to the horizon.
- Vertical Line: Extends up and down, perpendicular to horizontal lines.
- Ray: A straight path starting at a point and extending infinitely in one direction.
- Protractor: A mathematical instrument used for measuring angles in degrees.
- Midpoint: The exact middle point of a line segment.
- Angle: Formed by two rays meeting at a common endpoint, known as the vertex.
- Reflex Angle: Measures more than 180 degrees but less than 360 degrees.
- Perpendicular Lines: Two lines that intersect to form right angles (90 degrees).
- Segment: A portion of a line with two defined endpoints.
- Acute Angle: Measures greater than 0 degrees but less than 90 degrees.
- Intersection: The point where two lines cross each other.
- Finite: Describes a line segment or shape that has a specific endpoint.
- Vertical Angles: Angles opposite each other at the intersection of two lines.
- Supplementary Angles: When two angles sum up to 180 degrees.
- Complementary Angles: When two angles sum up to 90 degrees.
- Parallel Lines: Lines that never intersect and remain equidistant apart.
- Infinite: Describes a line or path that continues endlessly in both directions.
- Obtuse Angle: Measures more than 90 degrees but less than 180 degrees.
- Line: A straight path that extends infinitely in both directions.
- Vertex: The point at which two rays or line segments meet to form an angle.
- Symmetry: A property where one half of a figure is a mirror image of the other half when folded.
- Right Angle: An angle that measures exactly 90 degrees, equivalent to one quarter of a circle.
- Degree: A unit of measurement used to quantify angles.
