Geometrical instruments are used in drawing geometric figures such as triangles, circles, quadrilaterals, polygons etc. with given measuremets. A geometrical construction is the method of drawing a geometrical figure using an ungraduated ruler and a compass.
An angle bisector is a ray, which divides an angle in to two equal parts. The bisector of a line segment is a line that cuts the line segment into two equal halves. A perpendicular bisector is a line, which divides a given line segment into two equal halves and is also perpendicular to the line segment.
Construction of the bisector of a given angle:
Consider ∠DEF to construct the bisector.
Steps of construction:
Construction of the perpendicular bisector of a line segment:
Consider the line segment PQ to construct the perpendicular bisector.
Steps of Construction:
Consider ray PQ with P as the initial point. Construction of a ray PR such that it makes angle of 60° with PQ.
Steps of Construction:
