This book has been exclusively written to assist students preparing for technical drawing (plane and solid geometry) examinations at ordinary level.
It contains graphical solutions to questions from numerous plane and solid geometry topics which include: geometric construction, construction of
circles, blending of lines and curves, construction of tangents onto circles, construction of polygons, enlargement and reduction of plane figures and
equivalent areas, scales, conic sections, isometric, orthographic, and oblique projection, loci, link mechanism, auxiliary views/projections, lines in
space, development of surfaces, & interpenetration of solid figures.
N.B; The solutions are not to Scale.
I sincerely hope this book will be of great aid to the students and teachers of technical drawing at ordinary level.
The manuscript has been carefully written and checked however, I apologize in advance for any mistakes that may have gone unnoticed and I shall be
grateful if they are pointed out to me. God bless you mightily!

My dear parents, Mrs. Alice Stella Kirya and the Late Kirya Fredrick, for their unwavering support and encouragement.
Bro. Edward Bukenya, former headmaster of St. Mary’s College Kisubi, Uganda, for the motivation and support towards the technical drawing
department.
My former students at St. Mary’s College Kisubi, Uganda, whom through classroom interaction and experience have enabled me to enhance my
teaching career.
Mr. C.F Wodulo Masaya; lecturer in mechanical engineering drawing at Buganda Royal Institute Mengo, Uganda, for editing this book.
Finally, to all teachers of technical drawing with whom I have shared ideas on how to improve the teaching of the subject.
