# In this lesson we learn how to find the intercepting arc lengths of two secant lines or two chords that intersect on the interior of a circle. We also find the angle

Secant: an extended chord, a coplanar straight line, intersecting a circle in two points. Semicircle : one of the two possible arcs determined by the endpoints of a diameter, taking its midpoint as center.

Circle/ellipse The superficial spalling shape was like a circle with the seal the rock underneath normal support structures (for example secant pile walls or. A large value for h producing a distant support for the secant is clearly not good, and a too forms the first quadrant of the unit circle as the feasible region. Mohrs cirkel, Mohr's circle.

In a circle, every point on the circle is at an equal distance from the centre O. In a secant, the line intersects the circle at two points. 9.4 Segment of a circle form by a secant We have seen a line and a circle. When a line meets a circle in only one point, it is a tangent.

The line segment inside the circle between P and Q is called a chord. If two secant lines contain chords AB and CD in a circle and intersect at a point P that is not on the circle, then the line segment lengths satisfy AP⋅PB = CP⋅PD.

The lines are called secants (a line that cuts a circle at two points). This also works if one or both are tangents (a line that just touches a circle at one point), but since two lengths are identical we don't write c×d or c×c we just write c 2:
The secant can also be calculated using the inverse of the cosine.

### A. is the secant line on the below circle.

Let R be the radius of the arc which forms part of the perimeter of the segment, θ the central angle subtending the arc in radians , c the chord length , s the arc length , h the sagitta ( height ) of the segment, and a the area of the segment.
