- 2. a geometric shape characterized by having three unequal side lengths and three unequal interior angles. This makes it distinct from other triangles.
- 5. a fundamental concept in mathematics, representing a precise location in space with no dimensions, often depicted as a dot. It has no length, width, or height, making it the building block for defining lines, shapes, and volumes in geometry.
- 7. a geometric concept representing a line extending indefinitely from a single point, with direction but no specific length. used to describe the path along which light, heat, or other forms of energy travel.
- 9. points that lie within the same plane, meaning they can be contained on a flat surface without extending above or below it. In other words, they can all be connected by a single, straight line without leaving the plane.
- 12. multiple straight lines that lie on the same line, with no deviation, creating a shared path or trajectory in space. These lines possess identical directionality and can be extended infinitely in both directions along their common path.
- 14. an angle that is less than 90 degrees. For example, an angle that is 42 degrees
- 17. a polygon with three sides and three angles, formed by connecting three non-collinear points in a plane. Its properties vary depending on the lengths of its sides and the measures of its angles.
- 18. a point where two or more lines, edges, or curves meet, defining a corner or intersection within a geometric shape. It represents an entity such as a node in a network, with edges connecting vertices to represent relationships or connections between them.
- 19. a polygon with four sides and four vertices. Its interior angles sum up to 360 degrees.
Down
- 1. a flat, two-dimensional surface that extends infinitely in all directions, characterized by containing an infinite number of points and being completely flat. It is defined by any three non-collinear points within it, forming a unique, unbounded surface.
- 3. a geometric figure formed by two rays with a common endpoint. Measured in degrees or radians
- 4. a geometric shape characterized by three equal sides and three equal angles, each measuring 60 degrees. Its symmetrical properties make it a fundamental shape in geometry and architectural design.
- 6. a geometric figure with two sides of equal length and two corresponding angles of equal measure, making it symmetrical along its central axis. Its third side and angle may vary in size, but the equal sides give it a distinctive triangular shape.
- 8. a quadrilateral with opposite sides parallel and equal in length, forming two pairs of parallel sides. Its opposite angles are also equal, while adjacent angles are supplementary.
- 10. describes geometric figures or objects that have the same shape and size. Can be superimposed perfectly onto one another.
- 11. a line, ray, or segment that divides an angle or a line segment into two equal parts, creating two congruent angles or segments. serves as the geometric midpoint, ensuring equality and balance within the divided elements.
- 13. a closed geometric figure consisting of straight lines joined together to form a shape with three or more sides. Each side intersects exactly two other sides, and its interior angles sum up to specific values depending on the number of sides.
- 15. an angle that is more than 90 degrees. For example, an angle that is 142 degrees
- 16. an angle that is 90 degrees. For example, a 90-degree angle
- 20. a one-dimensional geometric figure that extends infinitely in both directions, composed of an infinite number of points arranged sequentially. It has no width or thickness, only length.
