Which undefined term is used to define an angle ?
enyata [817]

Point.

<h3>Further explanation</h3>
  • 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 express an angle with three points and a symbol ∠. The middle point represents constantly vertex. We can, besides, give angle names only with vertices. For example, based on the accompanying image, the angle can be symbolized 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.

<u>Note:</u>

Undefined terms are the basic figure that is undefined 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 marked with a capital letter and a dot.
  • A line represent 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 represents a planar 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.
