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.

• A. ii, i, iv, iii
• B. iii, i , iv, ii
• C. i, iii, iv, ii
• D. iv, iii, i, ii
