Steps given are to draw an involute of a given pentagon ABCDE. Arrange the steps. i. B as centre and radius AB, draw an arc cutting BC –extended at 1. ii. The curve thus obtained is the involute of the pentagon. iii. C as centre and radius C1, draw an arc cutting CD extended at 2. iv. Similarly, D, E, A as centres and radius D2, E3, A4, draw arcs cutting DE, EA, AB at 3, 4, 5 respectively.

Geometrical Construction topics include: Parallel & perpendicular lines construction, drawing regular polygons and tangents, ellipse construction, parabola and hyperbola construction, cycloidal curves and spiral construction. Geometric construction is the process of creating geometric objects using a compass and a straightedge. It is a part of pure geometry, which does not use numbers, formulae, or a coordinate system.  Geometric construction involves drawing lines, line segments, shapes, circles, and other figures accurately using a ruler, a compass, or a protractor.  Related...
