Study Notes
Key Components of Construction Problems
- Four essential parts: Given, Required, Construction, Proof.
Locus of Points
- Inclusive & Exclusive: Terms relating to the definition and parameters of a locus of points.
Geometric Constructions
- Construction 1: Method to divide a line into five equal segments.
- Construction 2: Technique to construct a tangent line from an external point R to a circle.
- Construction 3: Procedure for circumscribing a circle around a given triangle.
- Construction 4: Method to create a tangent line to circle O at point P, which lies on the circle.
- Construction 5: Steps to build a right triangle when a leg and the opposite acute angle are provided.
- Construction 6: Technique to construct an isosceles triangle with specified leg length and base.
Loci Related to Circles and Lines
- Locus of points outside a circle: Defined as a circle concentric to the original with a radius that is d units larger.
- Locus of centers of tangent circles: A line parallel to two given lines, situated midway between them.
Interior Points and Distances
- Distance and Location: The locus of points within square ABCD that are equidistant from sides AB and BC relates to diagonal BD (excluding points B and D).
- Complex Loci: Defined by conditions such as two inches away from a line and three inches from a point.
Perpendicular and Equidistant Points
- Locus formed by intersections: Two points where the perpendicular bisector of segment AB intersects with a circle centered at point A with a radius of 5 inches.
- Locus of points equidistant from two circles: Defined by a circle that is concentric to the original circles and set parallel lines eight inches away from line AB.
