StepExampleDescription
1Triangle ABC Start with triangle ΔABC.
2Triangle ABC with perpendicular bisector of side AB. Draw a perpendicular bisector of one of the sides. In this case, the perpendicular bisector of AB is drawn.
3Triangle ABC with perpendicular bisector of side BC. Draw a perpendicular bisector of another side. In this case, the perpendicular bisector of BC is drawn.
4Triangle ABC with intersection of the perpendicular bisectors labeled point D. Label the intersection of the perpendicular bisectors as point D.
5Triangle ABC with circumscribing circle drawn with center D and radius DA. Draw a circle with center D and radius DA.
