How to fill out reference triangles and reciprocal trig functions
How to fill out reference triangles and reciprocal trig functions
01
Start by identifying the angle you are working with (usually in degrees or radians).
02
Draw a right triangle where one angle is your given angle.
03
Label the sides of the triangle: the opposite side to the angle, the adjacent side to the angle, and the hypotenuse, which is the longest side.
04
Use the definitions of the primary trigonometric functions (sine, cosine, tangent) based on the sides of the triangle:
05
- Sine (sin) = opposite/hypotenuse
06
- Cosine (cos) = adjacent/hypotenuse
07
- Tangent (tan) = opposite/adjacent.
08
For reciprocal trigonometric functions, take the reciprocals of the primary functions:
09
- Cosecant (csc) = 1/sin
10
- Secant (sec) = 1/cos
11
- Cotangent (cot) = 1/tan.
12
Ensure all angles and sides are in the correct ratio to accurately represent the triangle.
13
Practice with different angles to become familiar with various reference triangles.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
What is reference triangles and reciprocal trig functions?
Reference triangles are right triangles used to define the values of trigonometric functions based on the angles. Reciprocal trig functions are functions that are inverses of the primary trig functions, such as cosecant (csc), secant (sec), and cotangent (cot).
Who is required to file reference triangles and reciprocal trig functions?
Students studying trigonometry or related fields are typically required to understand and use reference triangles and reciprocal trig functions in their coursework or assessments.
How to fill out reference triangles and reciprocal trig functions?
To use reference triangles, identify the angle, determine the lengths of the sides based on the angle, and then use these lengths to calculate sine, cosine, and tangent. For reciprocal trig functions, take the reciprocal of these values.
What is the purpose of reference triangles and reciprocal trig functions?
The purpose of reference triangles is to provide a visual and geometric means to understand the properties of trigonometric functions, while reciprocal trig functions help to establish relationships between different angles and sides in trigonometric calculations.
What information must be reported on reference triangles and reciprocal trig functions?
The information typically includes the angle measure, the lengths of the sides of the triangle, the values of sine, cosine, and tangent, as well as their respective reciprocal values: cosecant, secant, and cotangent.
