ray line that start from point A
arc arc from point A to point B

People also ask, what is the symbol for Ray?

A ray is also a piece of a line, except that it has only one endpoint and continues forever in one direction. It could be thought of as a half-line with an endpoint. It is named by the letter of its endpoint and any other point on the ray. The symbol → written on top of the two letters is used to denote that ray.

What is line segment and line?

In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.

### What is the sign of perpendicular?

### What is a perpendicular line?

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.

### Is there a symbol for intersecting lines?

Straight lines that cross each other at some point are called intersecting lines. These lines will intersect at one point only over their entire length. There is no symbol to use when naming intersecting lines.
