- 6. The angle between adjacent sides of a rectilinear figure.
- 7. Are coplanar straight lines that do not intersect at any point.
- 9. A fundamental relation in Euclidean geometry among the three sides of a right triangle.
- 10. The angle of interest in a triangle and it is not one of the two sides that form the angle.
- 12. A eight triangle with some regular feature that makes calculations on the triangle easier, or which simple formulas exist.
- 15. The longest side of a right triangle, opposite the right angle.
- 16. The trigonometric function that for an acute angle is the ratio between the leg opposite the angle when it is considered part of a right triangle and the hypotenuse.

Down
- 1. Is the branch of mathematics that is concerned with calculating the angles of triangles of the lengths of their sides.
- 2. Is a fact or a rule written with mathematical symbols. Man's best friend
- 3. A theorem in which all three sides of a triangle are congruent to the corresponding sides of another triangle, the triangles are congruent.
- 4. A theorem in which if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
- 5. Represent the parts of a whole or collection of objects.
- 8. A congruence theorem where it involves two angles and a non-included side.
- 11. The same size and shape.
- 13. The ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle.
- 14. A trigonometric function that for an acute angle is the ratio between the leg adjacent to the angle when it is considered part of a right triangle and the hypotenuse.
- 18. The √ symbol that is used to denote square root or nth roots.
