WebThe intersecting chords theorem can be used to help students understand the relationship between the segments of intersecting chords. ... For example, students could say: ... WebTheorem 6 : Alternate Segment theorem Statement. If a line touches a circle and from the point of contact a chord is drawn, the angles between the tangent and the chord are respectively equal to the angles in the corresponding alternate segments. Proof. Given : A circle with centre at O, tangent AB touches the circle at P and PQ is a chord.
WebDescription. 1. Let’s start with the circle with centre C. The line AB is a chord and CE is a radius. The lines CE and AB intersect at the point D at 90 degrees to one another because they are perpendicular. 2. We then draw the lines AC and BC. The length AC = BC as they are both radii of the circle. Web4. Theorem 4: The line that is drawn through the center of the circle to the midpoint of the chords is perpendicular to it.In other words, any line from the center that bisects a chord is perpendicular to the chord.. 5. …
