Study Notes
Triangles
- An equilateral triangle is defined by having three equal sides and angles.
- An obtuse triangle is a type of triangle that has one angle exceeding 90 degrees.
Foundations of Geometry
- Points, lines, and planes are the fundamental building blocks that form the foundation of spatial understanding and analysis in geometry.
Geometric Concepts
- Lines and planes provide a framework for defining and analyzing geometric shapes and structures.
- Angles measure the amount of rotation between two lines or planes within geometrical space.
Transformations
- Translation in geometry involves moving a shape from one location to another without changing its size or orientation.
- Rotation in geometry involves turning a shape around a fixed point or axis.
3D Geometry
- The defining feature of prisms is that they have two identical faces that are parallel to each other.
- Cones in 3D geometry taper from a circular base to a point.
Coordinate Geometry
- The Cartesian plane is a two-dimensional grid used to locate points in coordinate geometry, providing a visual representation of geometric relationships and relationships between shapes.
