Lesson: Perpendicular Bisector of a Chord Mathematics • Third Year of Preparatory School

Students will be able to

• understand that the straight line passing through the center of a circle and the midpoint of a chord is perpendicular to this chord and solve problems to find unknown lengths and angles,
• understand that the straight line passing through the center of the circle, which is also perpendicular to a chord, bisects this chord and solve problems to find unknown lengths,
• understand that the perpendicular bisector of any chord in a circle passes through the center of this circle.
