Across 5. angles whose measures sum to 90° 7. a triangle whose three angles are in the ratio 1 : 1 : 2, adding up to 180° 8. angle between a horizontal line and the line joining the observer's eye to some object beneath the horizontal line. 11. the angle that has a cosine equal to a given number. 12. relationships between the lengths of their sides and the angles between those sides 13. adjacent / hypotenuse 14. the angle that has a tangent equal to a given number. 15. the side opposite of the right angle 16. next to the hypotenuse 17. a triangle whose three angles are in the ratio 1 : 2 : 3 19. The angle formed by the horizontal and the line of sight to an object above the horizontal 20. two sides are equal in length also has two angles of the same measure

Down 1. the smallest leg on a triangle 2. the angle that has a sine equal to a given number. 3. the side opposite of the right angle 4. opposite / adjacent 6. right triangle with some regular feature that makes calculations on the triangle easier 9. across from the hypotenuse 10. opposite / hypotenuse 18. the longest side on a triangle
