of a Circle

By Anthony Laude

LLANO TV

Objectives:

By Anthony Laude

a. Define the secants, tangents, segments and sectors of a circle.

​​ b. Name the secants, tangents, segments, and sectors of a circle.

​c. Value accumulated knowledge as means of new understanding.

Tangent

By Anthony Laude

A line that passes through exactly one point on a circle.

​

J O K

E

The point of intersection of the line and the circle is called the point of tangency

Fill in the Blank

It is a line which is coplanar with the circle and intersects it in at most one point.

Open Ended

The point where the tangent intersects the circle.

Secant

By Anthony Laude

It is a line that intersects a circle at exactly two points.

​

E F

S​

A secant contains a chord of a circle.

Fill in the Blank

It is a line that intersects a circle at exactly two points.

Open Ended

A secant contains a _____ of a circle

Secant and Tangent Segments

By Anthony Laude

Segments and rays that are contained in the tangent or intersect the circle in one and only one point is also said to be tangent to the circle.

Segment of a Circle

By Anthony Laude

is the region bounded by a chord and the arc subtended by the chord.

Sector of a Circle

By Anthony Laude

It is the portion of a circle enclosed by two radii and an arc.

It resembles a "pizza" slice.

The SHADED REGION is the sector of the circle Y.

Multiple Choice

It is the region bounded by a chord and the arc subtended by the chord.
