Constructions

Chapter Overview

This chapter focuses on precise geometrical constructions using only a ruler and compass. It includes bisecting angles, drawing perpendiculars, and constructing triangles with known sides and angles. These foundational skills build spatial reasoning and accuracy in geometry.

Important Keywords

  • Construction: Drawing geometric shapes using only compass and straightedge.
  • Bisect: To divide into two equal parts.
  • Perpendicular: Lines that intersect at 90°.
  • Equidistant: At the same distance from two or more points.
  • Triangle Construction: Drawing a triangle using specific measurements and angles.
