Down: 1) A triangle is acute if the square of the longest side is less than the sum of the squares of the two shorter sides, each angle is less than 90 3) An isosceles triangle with interior angles of 45, 45, and 90 degrees. 4) The trigonometric ratio of the length of the side opposite a given angle to the length of the side adjacent to it6) A mnemonic device used to remember the three primary trigonometric ratios7) A right triangle with interior angles of 30, 60, and 90.The side length rules are8) The trigonometric ratio of the length of the side opposite a given angle to the length of the hypotenuse9) The angle formed between a horizontal line of sight and an object located above that horizontal line, often forms a right-angled triangle 11)  The side of a right triangle that is across from a specific reference angle; it does not touch the vertex of that angle13)  The inverse function of sine used to find the measure of an angle when the lengths of the opposite side and hypotenuse are known15) A ratio of the lengths of two sides of a right triangle, relating them to one of the acute angles 16) The side of a right triangle that is next to a specific reference angle and helps form it, but is not the hypotenuse18) A Greek letter commonly used in mathematics as a variable to represent the measure of an unknown angle Across: 2)  The trigonometric ratio of the length of the side adjacent to a given angle to the length of the hypotenuse5) A triangle is obtuse if the square of the longest side is greater than the sum of the squares of the two shorter sides, one angle is greater than 90 10)  The inverse function of tangent used to find the measure of an angle when the lengths of the opposite side and adjacent side are known12) The angle formed between a horizontal line of sight and an object located below that horizontal line14) A branch of mathematics that studies the relationships between the side lengths and angles of triangles.17) The inverse function of cosine used to find the measure of an angle when the lengths of the adjacent side and hypotenuse are known19) A theorem used to determine the type of triangle based on its side lengths. It states that if the square of the longest side ( ) is equal to the sum of the squares of the two shorter sides ( + ) then the triangle is a right triangle.
