Study Notes
Geometric Figures
- Geometry analyzes properties, measurements, and constructions of flat figures (angles, triangles, rectangles) and solid figures (cubes, pyramids, spheres).
- A geometric solid is defined by the space it occupies.
- Each geometric solid has six surfaces, known as faces.
- The intersection where two surfaces meet is called an edge.
- A line is formed at the intersection of any two surfaces.
- A point represents the intersection of any two lines.
- A straightedge is an instrument used for drawing straight lines.
- A surface is considered a plane if a straight line connecting any two points lies entirely within that surface.
- Two points are sufficient to determine a straight line.
- A broken line consists of multiple consecutive straight lines.
Principles
- The straight line is recognized as the shortest distance between two points.
- Exactly one straight line can be constructed between two distinct points.
- Two straight lines can intersect at no more than one single point.
- Quantities (lines) that are equal to a common quantity are equal to one another.
Axioms
- The entirety of a whole is equivalent to the aggregate of all its individual parts.
- A whole is always larger than any of its constituent parts.
- Adding equal quantities to equal quantities results in equal sums.
- Subtracting equal quantities from equal quantities yields equal remainders.
- The doubles of equal quantities remain equal.
- Halves of equal quantities are also equal.
- If the first of three quantities is greater than the second, and the second is greater than the third, then the first is greater than the third.
- All straight angles are defined as equal.
Definitions
- Equal segments: segments are considered equal when their endpoints can align perfectly.
- Midpoint is defined as the point that divides a segment into two equal parts.
- A line segment is said to be trisected when it is divided into three equal parts by two distinct points.
- An angle is created by two straight lines that originate from the same point.
