Answer:
In geometry, there are several terms that are defined mathematically. Some of these terms include:
1. Point: In geometry, a point is defined as a location in space with no size or dimension. It is often represented by a dot and has no length, width, or height.
2. Line: A line is a straight path that extends infinitely in both directions. It is defined by two points and can be represented by a straight line segment with arrows on both ends.
3. Angle: An angle is formed when two rays share a common endpoint, called the vertex. It is measured in degrees and is defined by the amount of rotation between the two rays.
4. Circle: A circle is a geometric shape that consists of all the points in a plane that are equidistant from a fixed center point. It is defined by its radius (the distance from the center to any point on the circle) or its diameter (twice the radius).
5. Triangle: A triangle is a polygon with three sides and three angles. It is defined by the lengths of its sides and the measures of its angles. There are different types of triangles, such as equilateral (all sides and angles are equal), isosceles (two sides and two angles are equal), and scalene (all sides and angles are different).
These terms are mathematically defined in geometry and provide a foundation for understanding various geometric concepts and principles.
