Circle theorem perpendicular

WebSep 15, 2024 · We need a different procedure for acute and obtuse triangles, since for an acute triangle the center of the circumscribed circle will be inside the triangle, and it will be outside for an obtuse triangle. Notice from the proof of Theorem 2.5 that the center \(O\) was on the perpendicular bisector of one of the sides (\(\overline{AB}\)). WebThere are two basic formulas to find the length of the chord of a circle which are: Formula to Calculate Length of a Chord. Chord Length Using Perpendicular Distance from the Center. Chord Length = 2 × √ (r 2 − d 2) Chord Length Using Trigonometry. Chord Length = 2 × r × sin (c/2) Where, r is the radius of the circle.
