Draw a circle and two lines parallel to a given line such that one is a tangent and the other, a secant to the circle

Solution:

Two or more lines that lie in the same plane and never intersect or meet each other such that the distance between them remains the same at every point are known as parallel lines.

Tangent line or tangent in geometry means a line or plane that intersects a curve or a curved surface at exactly one point.

Secant in geometry means a line that intersects two points on an arc/circumference of a circle.

Step (i) Draw a circle.

Step (ii) Draw one tangent and one secant to the circle parallel to the given line.

As shown in the diagram above, XY is the given line.

AB is the secant parallel to XY, AB || XY.

PQ is the tangent parallel to XY, PQ || XY.

Summary:

Thus, we have drawn a circle and two lines parallel to a given line such that one is a tangent and the other, a secant to the circle. XY is the given line, AB is the secant parallel to XY, AB ∥ XY, AQ is the tangent parallel to XY and PQ ∥ XY.
