Study Notes
Geometry Terms and Definitions
- Hierarchy: An arrangement of objects based on the relationships among their characteristics.
- Angle: Formed by two rays or lines sharing a common endpoint.
- Vertices (Vertex): The meeting point of two lines, creating an angle.
- Parallel Lines: Lines that never intersect, maintaining equal distance apart.
- Right Angle: Measures exactly 90 degrees, forming a perfect corner.
- Acute Angle: An angle measuring less than 90 degrees.
- Obtuse Angle: An angle measuring more than 90 degrees.
Two-Dimensional Figures
- Two-Dimensional Figures: Flat shapes characterized by only length and width, lacking depth.
- Polygon: A closed figure with at least three straight sides.
- Parallelogram: A four-sided shape (quadrilateral) with two pairs of parallel sides.
- Quadrilateral: Any four-sided figure.
- Trapezoid: A four-sided figure with one pair of parallel sides.
Specific Types of Polygons
- Rectangle: A quadrilateral with four right angles, where opposite sides are equal and parallel.
- Square: A special type of rectangle with four equal sides and four right angles.
- Triangle: A three-sided figure with varying properties depending on its side lengths and angles.
Triangle Classifications
- Rhombus: All four sides are of equal length, with opposite angles being equal.
- Isosceles Triangle: A triangle with two equal sides and angles.
- Equilateral Triangle: A triangle where all three sides and angles are equal (60 degrees each).
- Right Triangle: Contains one angle that measures 90 degrees.
- Scalene Triangle: A triangle with no equal sides or angles.
- Acute Triangle: All three angles measure less than 90 degrees.
- Obtuse Triangle: Contains one angle that exceeds 90 degrees.
Other Geometry Concepts
- Regular Polygon: A closed figure with sides and angles that are all congruent.
- Irregular Polygon: A closed figure with no sides or angles that are congruent.
- Congruent: Refers to sides or angles that are of equal measure.
- Degree: A unit used to quantify the size of angles.
