Geometry – perpendicular bisectors to lines. Now, tap on the side of the triangle marked AB, then tap onto the perpendicular bisector picture. Enter into the Geometry icon. Draw a triangle. Tap on the second picture to open the drawing tools. The perpendicular bisector to AB will be drawn. Repeat the process on each of the 2 other sides of the triangle. The 3 perpendicular bisectors ALL intersect at a point. This point is called the circumcentre. Definition: Circumcentre is the Select Then tap on the screen to make a triangle appear, as shown below. Now select form the tasks in the adjacent ‘box’ Select Select View and then Zoom out gives a better picture of the triangle and the circumcircle.
