Right+Triangles



__ Let's learn vocabulary about the awesome right triangle __

Omg a triangle but not just any triangle....A RIGHT TRIANGLE! __perfect square__- the square of an integer

__square root__- the inverse of squaring a number

__irrational__- a number that cannot be expressed as the ratio a/b where be does not equal zero

__ distance __- The extent of space between points on a measured course



A right triangle consists of a 90 degree angle made up of two sides called legs and another side called the hypotenuse as shown by the picture above

__legs-__ in a right triangle, the two shortest sides

__hypotenuse__- the longest side which is opposite the right angle



__ midpoint __- a point on a line segment that divides it into two equal parts or the halfway point of a line segment

__ trigonometry __ - The branch of mathematics that deals with the relationships between the sides and the angles of triangles and the calculations based.

__ trigenomic ratio __ - a ratio that describes a relationship between a side and angle of a triangle

__ sine __- In a right triangle, the ratio of the length of the side opposite an acute angle to the length of the hypotenuse. __cosine__- In a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.

__ tangent __- of an acute angle, the ratio of the length of the right triangle opposite to the acute to the length of the leg adjacent to the angle

__ angle of elevation- __ formed by a horizantal line and a line of sight above it. It is used when you must look up at an object



__angle of depression-__ formed by a horizantal line and a line of sight below it. It is used when you must look down at an object
