Webon a circle. A diameter is a chord that contains the center of the circle. It is also the longest chord and is equal to twice the length of the radius . A secant is a line that intersects a circle in two points. A tangent is a line, ray or segment in the plane of the circle that intersects a circle in exactly one point, the point of tangency. WebCircumference – The perimeter of the circle. Tangent – A straight line that touches the edge of the circle. This makes a 90° angle with the radius at this point. Chord – A line across …

There are seven main types of musical scales, or modes. Each one consists of eight notes, combining whole and half steps in slightly different combinations to produce different feelings in the listener. Ionian (the major scale): W (hole step), W, H (alf step), W, W, W, H. Dorian: W, H, W, W, W, H, W.
WebIf two secant segments are drawn from a point outisde a circle, the product of the lengths (C + D) of one secant segment and its exteranal segment (D) equals the product of the lengths (A + B) of the other secant segment and its external segment (B).
