Parts of Right Triangles
What is the longest side of a right triangle called?
hypotenuse
What ratio do you use when you are given the opposite and hypotenuse?
sine
What type of trig functions do you use to find missing angles?
Inverse sine/cosine/tangent
What is the height of a flagpole that makes a 15.2m long shadow and has a a 38 degree angle of elevation from the ground?
11.9m
Find the angles if the hypotenuse is 5 cm and the opposite side is 3.5 cm
44.43 degrees
What is the pythagorean theorem and what does each part represent?
a2+b2=c2, where a and b are the legs and c is the hypotenuse.
What ratio do you use when you are given the two legs, opposite and adjacent side, of a right triangle?
tangent
What is the only ratio that does not use the hypotenuse?
tangent
