Step 1:Draw a line segment measuring one of the given base length

                        of the triangle.


Step 2: Draw a perpendicular bisector the line segment.

           NOTE:  Draw two intersecting arcs at 4 cm distance from points A and B

                          on either side of AB.

            

Step 3: Now join these arcs to get perpendicular bisector CD of AB.


Step 4: Join A and B to C to get the triangle ABC.
