What is a point?

A point is a fundamental element in geometry, representing a precise location in space with no size, shape, or dimension. It is often denoted by a dot and used as a building block for constructing geometric figures and shapes.

What is a line segment?

A line segment is a straight path that connects two points, with a definite beginning and end. It is the shortest distance between the two points on a line. It has a specific length and does not extend indefinitely in both directions like a line does.

What is a ray?

A ray is a geometric figure that consists of a single point called the endpoint, and extends indefinitely in one direction. It is symbolized by a line with an arrowhead on one end to indicate the direction in which it extends. Rays are commonly used in geometry to represent light rays, line segments that start at a specific point and continue in a particular direction.

What is an angle?

An angle is a figure formed by two rays or line segments that have a common endpoint. The point of intersection between the rays is called the vertex of the angle. The size of an angle is measured in degrees, with a full circle measuring 360 degrees. Different types of angles include acute (less than 90 degrees), right (exactly 90 degrees), obtuse (greater than 90 degrees but less than 180 degrees), and straight (exactly 180 degrees).

What is a polygon?

A polygon is a closed two-dimensional shape with straight sides. It is formed by connecting at least three line segments together. The sides of a polygon do not cross each other, and the angles between the sides are all less than 180 degrees.

What is a triangle?

A triangle is a basic geometric shape that consists of three sides and three angles, with the sum of all angles always equaling 180 degrees. It is a polygon with three vertices and three edges connecting them. Triangles can be classified based on the length of their sides (e.g., equilateral, isosceles, scalene) or the measure of their angles (e.g., acute, obtuse, right).

What is a quadrilateral?

A quadrilateral is a geometric figure with four sides and four angles.

What is a circle?

A circle is a two-dimensional geometric shape that consists of all points in a plane that are at a given distance, called the radius, from a fixed point, called the center. It is defined as the set of all points equidistant from the center, forming a closed curve.

What is symmetry?

Symmetry is a balanced arrangement of parts around a central point or axis, where one side mirrors the other side. It is a fundamental concept in mathematics and art that highlights an equal distribution of elements, shapes, or patterns on either side of a dividing line or point, creating a harmonious and visually appealing composition.

What is a coordinate plane?

A coordinate plane is a two-dimensional surface formed by two perpendicular number lines called axes, typically the x-axis (horizontal) and y-axis (vertical), that intersect at a point called the origin. The grid created by these axes divides the plane into four quadrants, with each point in the plane represented by an ordered pair of numbers, indicating its distance from the axes. This system allows for the precise location and graphing of points and shapes in mathematics and geometry.
