Tangent and radius theorem
Web2. In a circle, a radius that bisects a chord is perpendicular to the chord. 3. In a circle, the perpendicular bisector of a chord passes through the center of the circle. 4. If a line is tangent to a circle, it is perpendicular to the radius drawn to the point of tangency. Chord Theorems 1. In a circle or in congruent circles, congruent chords ...

Any tangent to a circle is perpendicular to the radius at the point of contact. The proof of this theorem relies on the fact that the shortest distance between a line and a point is the perpendicular distance between the two objects. In other words, the shortest line segment from the ...
WebA tangent makes an angle of 90 degrees with the radius of a circle, so we know that ∠OAC + x = 90. The angle in a semi-circle is 90, so ∠BCA = 90. The angles in a triangle add up to 180, so ∠BCA + ∠OAC + y = 180 … WebIn Euclidean plane geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior.Tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs.Since the tangent line to a circle at a point P is perpendicular to the radius to that …
WebExample 1: standard diagram. Points A A, B B, and C C are on the circumference of a circle with centre O O. DE DE is a tangent at point A A. Calculate the size of angle BAD B AD. Locate the key parts of the circle for the theorem. Here we have: The angle BCA=52°. B C A = 52 ° BCA = 52°. BC A = 52°. WebDec 6, 2024 · Tangent and radius of a circle meet at 90°. A tangent is a line that just touches the circle at a single point on its circumference. If we draw a radius that meets the …
WebExample 1: Consider a circle with center O given below. Find the value x using circle theorems. Solution: We are given a circle with a center O. Sine OS and OT are radii, OS = OT. Using the circle theorem 'The angle between the radius and the tangent at the point of contact is 90 degrees.', we have ∠OTP = 90°.
