What are Lines? A line is a straight one-dimensional figure, that extends in the opposite directions infinitely. A line can be horizontal or vertical. It can be drawn from left to right or top to bottom. What are Angles? Angles are the shape that is formed when the endpoints of two rays meet at a single point.

Vertex Definition. A vertex in math is a point where two lines or rays meet forming an angle at that point and is denoted by uppercase letters like A, O, P, etc. The plural of vertex is vertices. In solid geometry, i.e., 3D geometry, shapes such as cubes, cuboids form several vertices. Whereas in 2D shapes such as polygons form only a vertex.
- Name the line shown in red. Solution. The red line goes through the points C and F, so the line is \(\overleftrightarrow{CF}\). The section between any two points on a line is called a line segment.
- Identify each line and line segment in the picture below. Solution. Two points define a line, and a line is denoted with arrows. There are two lines in this picture: \(\overleftrightarrow{CE}\) and \(\overleftrightarrow{BG}\).
- Identify each point and ray in the picture below. Solution. There are four points: A, B, C, and D. There are also three rays, though only one may be obvious.
- Label each angle below as acute, right, or obtuse. Solution. You can start by identifying any right angles. ∠GFI is a right angle, as indicated by the corner mark at vertex F.
The equation of Line 1 1 is y=x+1 y = x + 1 and the equation of Line 2 2 is y=x-5. y = x − 5. The slope of Line 1 1 is 1 1 and the slope of Line 2 2 is 1. 1. Notice how the slopes are the same. Parallel lines will always have the same slope because they will not intersect. Let’s look at another example.
The point at which they cross is known as the point of intersection close point of intersection The location where two or more lines meet.. If two lines meet at a right angle close right angle An ...
Intersect is a term used to describe two or more lines that cross each other to form an angle. When two lines intersect, they create four distinct angles—two acute angles and two obtuse angles. These angles are measured in degrees (°) and can range anywhere from 0° (no angle) to 180° (a straight line). The point at which the two lines ...

A point is a dimensionless shape, since it represents a dot only, whereas a line is a one-dimensional shape. Both points are lines used to draw different shapes and sizes in a plane. These shapes can be two-dimensional or three-dimensional. What is a Point? A point is a dot in a plane or a piece of paper.
