Study Notes
Circle and Related Concepts
- Center: Point equidistant from all points on a circle.
- Circle: Round figure defined by points at an equal distance from the center.
- Circumference: Total distance around a circle.
- Diameter: Line segment that runs through the center, connecting two points on the circle's boundary.
- Radius: Line segment from the center to any point on the circumference, half of the diameter.
Geometric Figures
- Composite Figure: Formed by combining simpler geometric shapes.
- Regular Pyramid: Pyramid with a base that is a regular polygon and lateral faces that are congruent isosceles triangles.
Surface and Volume Measurements
- Lateral Face: Any face of a polyhedron that is not a base.
- Lateral Surface Area: Total area of all lateral faces in a solid object.
- Surface Area: Overall area covering the external surface of an object.
- Volume: Total space contained within a solid object.
Special Terms and Formulas
- Semicircle: Half of a circle.
- Slant Height: Height measured from the base to the apex along the lateral face of a pyramid.
- Pi (π): Mathematical constant representing the ratio of circumference to diameter, approximately 3.14 or expressed as 22/7.
Formulas
- Area of a Circle: Calculated using the formula A = πr², where r is the radius.
- Circumference of a Circle: Given by the formula C = 2πr, where r is the radius.
