# Perpendicular Bisector

Tendopro

## Construction

Construct a line perpendicular to CB.
1. Use the Circle with Centre through Point tool to draw circles centred at B and C with radii BC.
2. Using the Intersect tool, mark where these 2 circles intersect.
3. Use the Line tool to draw a line segment between these points of intersection.
4. Use the Intersect tool to mark where this new line intersects BC.
5. Use the Distance or Length tool to measure the distance between the point of intersection and both B and C.
6. Use the Angle tool to measure the size of the angle at this pint of intersection. Click point B, than the point of intersection and then the top most point of your constructed line segment.
