Determine if xy is tangent to circle z

The distance between yz is 5cm.

Tangent on circle

Tangent is a line that touches the circle and passes through at a touching point.

Given

xy is a tangent line on the circle.

and circle of radius r and center z.

Step by step explanation

The tangent of the circle and radius of the circle meet at 90 degrees.

Hence, a right-angle triangle is formed so we can apply the Pythagoras theorem.

Let the Length of the line is 4cm

And Radius of the circle is 3cm

Then

Here,

xz = 3 cm

xy = 4 cm

Then

Hence, the distance between yz is 5cm.

Hi there!

When a segment is tangent to a circle, it is perpendicular to the radius. If you're given measurements, like the image below, you can use the pythagorean theorem to determine if the triangle is a right triangle. If the triangle is right, then the segment is tangent to the circle.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

For being nice i appreciate it but abc
