This exercise deals with basic knowledge of construction of triangles, rectangles and squares etc. We use this knowledge in our everyday life, for example in woodworking, graphic art, pattern making and metal arts. Geometrical figures, when intermixed, give an artistic look. In order to construct these figures we need a pair of compasses, Set Squares, Dividers and a straight edge. If the objects, for which we want to draw a geometrical design, are large in size, we may choose some suitable scale of reference so that the object can be designed on the available piece of paper.

Construction of a Triangle:

Construction of a Triangle when two sides and the angle in between are given:

Draw one side AB, equal to the size given

At point A on the line AB, make the given angle and draw a line.

Cut the line at C equal to the size of the second side.

Draw a line joining the points B and C.

The triangle ABC constructed is the required Triangle.
