In reality, however, the long-term mental health state of many cardiac arrest survivors is not typically considered or assessed, the researchers write in their report, which appears in the journal Resuscitation.
What is the difference between Chord, Tangent and Secant? â¢ A chord is a line segment and both secant and tangents are straight lines. â¢ Chord is a line segment with the end points lying on a curve while a secant is a line passing through exact two points on a curve. â¢ A tangent is a line that just touches and passes through a point on a curve. It is a special case of secant where the two points on the curve overlap.
Tangent-Chord Angle Theorem The measure of an angle formed by a tangent and a chord drawn to the point of tangency is one-half the measure of the intercepted arc. m mABCAC211 is the chord, CD is the tangent m mBCBC212chord, CDis the tangent m mAECEC213 is the chord, CD is the tangent 2 3.erpendicular to a Chord Theorem The perpendicular from the center of a circle to a chord is the bisector of the chord. Chord Distance to Center Theorem Two congruent chords in a circle are equidistant from the center of the circle.
