geometry

2. : a line that starts at a single point (its endpoint) and extends infinitely in one direction.
5. : the longest side of a right triangle, and it's always opposite the right angle (the 90-degree angle).
8. : a straight, one-dimensional figure with no thickness that extends infinitely in both directions
10. : the inverse of a conditional statement negates both the hypothesis and the conclusion.
11. : a flat, two-dimensional surface that extends infinitely in all directions
14. : a four-sided shape (quadrilateral) with all four sides equal in length.
16. : a fundamental statement or assumption that is accepted as true without proof.
17. : a quadrilateral (a four-sided shape) with four equal sides and four right angles

1. : a quadrilateral with exactly one p
3. : a line segment drawn from a vertex of the triangle to the line containing the opposite side, and it is perpendicular to that line.
4. : congruence, meaning exactly the same shape and size, even when rotated or flipped
6. : a quadrilateral with two pairs of adjacent congruent sides
7. : the measure of the surface inside a two-dimensional figure, typically measured in square units.
9. : a figure formed by two rays that share a common endpoint, called the vertex
11. : the total distance around the outside of a two-dimensional shape, specifically a polygon
12. : formed by reversing the hypothesis and conclusion of the original statement
13. : a polygon with four sides, four angles, and four vertices
15. : a polygon with six sides and six interior angles.
