Solving Right Triangles Flashcards
1
Q
What is a Trigonometric Ratio?
A
A ratio of two sides of a right triangle.
2
Q
What is Sine?
A
The ratio of the lengths of the leg opposite the angle and the hypotenuse.
3
Q
What is Cosine?
A
The ratio of the lengths of the adjacent leg and the hypotenuse.
4
Q
What is Tangent?
A
The ratio of the lengths of the opposite leg and the adjacent leg.
5
Q
How do you solve for missing measures?
A
You use Sin/Cosine/Tangent and any angles/sides you are given.
6
Q
What are the Inverse Trigonometric Functions?
A
If sin A=x, then (sin^-1)x=A
If cos A=x, then (cos^-1)x=A
If tan A=x, then (tan^-1)x=A
7
Q
What is the Distance Formula?
A
z=sqrt(((x2-x1)^2)+(y2-y1)^2)))
