## How do you find the locus point of intersection of tangents?

The locus of the point of intersection of tangents to the circle x=acosθ,y=asinθ at the points, whose parametric angles differ by π2 is. a pair of straight lines. a straight line. a circle.

**What do you called the point of intersection between the circle and a tangent line?**

The point where the tangent line intersects the circle is called the point of tangency. A tangent line to a circle is perpendicular to the radius of the circle drawn to the point of tangency.

**Can there be two tangents at a point?**

If a function is differentiable at a point, it can only have one tangent line at that point. However, if a function is convex and not differentiable at a point, it can have multiple tangent lines at that point. Consider . The lines and both intersect the function at the origin, and nowhere else.

### What is the point of intersection in tangent line?

In set theory, the intersection of two sets is the collection of all things common to both sets. Therefore, the intersection of a circle and a tangent line is a single point.

**How many points does a tangent intersect a circle?**

one point

The tangent of a circle is a line or line segment that intersects a circle at only one point. Line A B AB AB is a tangent of this circle.

**How many points of intersection does a secant line and a circle have?**

two points

In geometry, a secant is a line that intersects a curve at a minimum of two distinct points. The word secant comes from the Latin word secare, meaning to cut. In the case of a circle, a secant intersects the circle at exactly two points.

## What is a segment between the center of a circle and a point on the circle?

Radius. A line segment between the center and a point on the circle or sphere. The word radius also refers to the length of this segment.

**Are two intersecting tangents equal?**

Two tangents from a common point are congruent! Just drag the points around the screen and you’ll see that–no matter what–the lengths of the tangents, are always equal. …

**How do you find the point of intersection?**

How Do I Find the Point of Intersection of Two Lines?

- Get the two equations for the lines into slope-intercept form.
- Set the two equations for y equal to each other.
- Solve for x.
- Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y.

### What is the formula for point of intersection?

So set one equation equal to the other, and solve for x. Then substitute that x value back into either equation to get the y value. You then have the x and y values of the point of intersection.
