What is tangent arc?

A tangent arc is an arc that is tangent to a straight line or another arc at only one point. It is commonly used in geometry to determine the angles and lengths of various lines and angles in a geometric shape or figure.

In a circle, a tangent arc is formed when a line intersects the circle at only one point, forming a right angle with the radius of the circle at that point. The arc is tangent to the line and is the portion of the circle that lies between the two points of intersection between the line and the circle.

Tangent arcs can also be used in other shapes, such as ellipses and hyperbolas, where they serve a similar purpose of providing information about the angles and lengths of lines within the shape.

Overall, tangent arcs are a useful tool in geometry and can be used to analyze and solve various geometric problems.
