Topics in Geometric Constructions
Construction of Similar Triangles
- Similar triangles have corresponding sides in the same proportion and corresponding angles equal
- Two methods exist: when vertices are distinct and when one vertex is common
- The scale factor determines the ratio of corresponding sides
Construction of Tangents to a Circle at a Point on the Circle
- Two methods: using the center and without using the center
- A tangent is perpendicular to the radius at the point of tangency
- Method 1: Draw radius to the point, then construct perpendicular
Construction of Tangents from External Point to a Circle
- From any external point, exactly two tangents can be drawn to a circle
- Both tangents from external point are equal in length
- Construction uses the property that angle in semicircle is 90°
Key Construction Principles and Theorems
- All constructions use only compass and straightedge (unmarked ruler)
- Constructions must be reproducible and geometrically accurate
- Each construction is based on fundamental geometric theorems
