  1. 5. The trigonometry ratios. The acronym that helps you remember the steps to solve trig.
  2. 7. you look down at an object. The angle your line of sight makes with a horizontal line is called the ____.
  3. 9. It is a ratio of the lengths of two sides in a right triangle. You will use this to find the measure of a side or an acute angle in a right traingle.
  4. 10. In a right triangle, a __ side is the one across from a given angle.
  5. 12. Itis an isosceles right triangle. It can be formed by cutting a square in half.
  6. 14. In a right triangle, two angles are ___ if they have a common side. With a common vertex.
  7. 15. In a right triangle. The square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the leg.
  8. 18. is the value received when the length of the side opposite of angle is divided by the length of the side adjacent to angle theta. It is very commonly abbreviated as tan.
  9. 19. It is a triangle in which one angle is a right angle or two sides are perpendicular. The relation between the sides and other angles of the right triangle is the basis for trigonometry.
  10. 20. the sum is 90 degrees. One of the most important angles in geometry. Represented by a box.
Down
  1. 1. you can find the tangent of an acute angle measuring 30, 45, or 60 degrees by applying what you know about ____.
  2. 2. Can be formed by dividing an equilateral triangle in half. The hypotenuse is twice as long as the shorter leg.
  3. 3. if you look up at an object. The angle your line of sight makes with a horizontal line is called the ___.
  4. 4. when the sum of two angles is 90 degrees.
  5. 6. If the square of the length of the longest side of a triangle is equal to the sum of the squares of the lengths of the other two sides. Then the triangle is a right triangle.
  6. 8. It is the longest side of a right-angled triangle, the side opposite the right angle. The length of the ____ can be found using the Pythagorean theorem.
  7. 11. It is a right triangle that consists of two equal-length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent.
  8. 13. the ratio of the lengths of the legs in a right triangle is constant for a given measure. This ratio is called the ___ of the angle.
  9. 16. Used mainly in trigonometry. It is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle's hypotenuse.
  10. 17. It is the ratio of the length of the side of the triangle adjacent to the angle to the length of the triangle's hypotenuse. It is mainly used in trigonometry.
