Click on the flashcard to see the answer
What is a point?
A point is a precise location in space with no dimensions.
Define a line.
A line is a straight path that extends indefinitely in both directions.
What is a line segment?
A line segment is a portion of a line with two defined endpoints.
Define a ray.
A ray is a portion of a line that starts at a specific point and extends infinitely in one direction.
What is an angle?
An angle is the union of two rays with a common endpoint.
Define parallel lines.
Parallel lines are two or more lines in the same plane that never intersect.
What is a perpendicular line?
A perpendicular line is a line that intersects another line at a 90-degree angle.
Define a polygon.
A polygon is a closed figure made up of line segments.
What is a triangle?
A triangle is a polygon with three sides and three angles.
Define a quadrilateral.
A quadrilateral is a polygon with four sides and four angles.
What is a circle?
A circle is a set of all points in a plane that are equidistant from a fixed center point.
Define perpendicular bisector.
A perpendicular bisector is a line or segment that cuts another line segment into two equal parts at a 90-degree angle.
What is a diagonal?
A diagonal is a line segment that connects two nonadjacent vertices in a polygon.
Define symmetry.
Symmetry is a balanced arrangement of parts or shapes that are identical or similar.
What is a tangent?
A tangent is a line or line segment that just touches a curve at a single point without crossing it.
