What value of x will make 4x-1=4x+7 true ?

Point.

Further explanation

This is one of the classic problems of Euclidean geometry.

The angle is determined by three points, we call it A, B, C, with A ≠ C and B ≠ C.

We denote an angle with three points and a symbol ∠.  The middle point is always the vertex.  We can also give angle names only with vertices. For example, based on the attached image, the angle can be denoted as ∠BAC, or ∠CAB, or ∠A.

Types of Angles  

• The acute angle represents an angle whose measure is greater than 0° and less than 90°.
• The right angle is an angle that measures 90° precisely.  
• The obtuse angle represents an angle whose measures greater than 90° and less than 180°.  
• The straight angle is a line that goes infinitely in both directions and measures 180°. Carefully differentiate from rays that only runs in one direction.

Note:

Undefined terms are the basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.

These key terms cannot be mathematically defined using other known words.

• A point represents a location and has no dimension (size). It is labeled with a capital letter and a dot.
• A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
• A plane is a flat surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.

Explanation:

A point is a location on the graph or at any surface.

A line is the distance between the two points that extends to infinite in both directions.

A ray is defined as the distance between the two points that extends to infinite in one direction.

Plane extends in two dimensions.
