Find Missing Sides Worksheets
In these free math worksheets, students learn to find missing sides of a right triangle using Trigonometry.
There are two sets of Find Missing Sides worksheets: Find missing sides of triangles Missing sides word problems
How to find missing sides using Trigonometry?
To find missing side lengths using trigonometry when given a side and an angle in a right triangle, we can follow these steps:
Identify the known side and angle: Label the sides of the triangle as opposite, adjacent, and hypotenuse in reference to the given angle. Mark the known side length and angle on the diagram.
Choose the appropriate trigonometric ratio: Use the acronym SOH CAH TOA to determine which trigonometric ratio to use based on the known and missing sides: SOH: Sine = Opposite/ Hypotenuse CAH: Cosine = Adjacent/ Hypotenuse TOA: Tangent = Opposite/ Adjacent
Set up the equation and solve: Substitute the known values into the chosen trigonometric ratio. Solve for the missing side length using algebraic manipulation.
Here are some examples:
Example 1: Given a right triangle with a hypotenuse of 10 cm and an angle of 30°, find the length of the side opposite the angle.
Solution: Known side: Hypotenuse = 10 cm Known angle: 30° Needed side: Opposite Trigonometric ratio: SOH (because we are looking for the opposite side) Equation: sin(30°) = Opposite / 10 Solve: Opposite = 10 * sin(30°) = 5 cm
Example 2: Given a right triangle with an adjacent side of 6 cm and an angle of 45°, find the length of the hypotenuse.
Solution: Known side: Adjacent = 6 cm Known angle: 45° Needed side: Hypotenuse Trigonometric ratio: CAH (because we are looking for the hypotenuse) Equation: cos(45°) = 6 / Hypotenuse Solve: Hypotenuse = 6 / cos(45°) = 8.49 cm

Trigonometry Worksheets
Trigonometry worksheets promote an understanding of trigonometry concepts. Students can use these worksheets to improve their skills in solving trigonometric problems. The questions included in the worksheet are based on solving trigonometric identities, deriving trigonometry formulas, understanding trigonometry elements such sines, cosines, etc.
Benefits of Trigonometry Worksheets
Trigonometry finds use in several real life applications such as architecture, music, data analysis, etc. Hence, students must be well versed in the topic. This can only happen with clear concepts and immense practice that is provided by trigonometry worksheets.
As the scope of trigonometry is very vast, thus the worksheets have a gradual increase in the level of difficulty. This makes sure that a student doesn't get confused and can assimilate information effectively. Another added feature of these worksheets is that they are flexible, enabling students to work at their own pace.

Why is trigonometry important.
When learning about trigonometry, many students struggle to understand how it is relevant in real life.
Studying the properties of triangles and calculating missing angles can seem like an arbitrary task, but it actually has many applications in the real world. From astronomy, to aviation, medicine and more, trigonometry allows many industries to function.
Essential Knowledge for Future Scientists
A solid knowledge of trigonometry is essential for any student who aspires to work in a scientific discipline.
Students will need to master trigonometry at GCSE level in order to study A-Level maths and sciences, subjects which they will need to secure a university place for engineering, medicine, and the sciences. Although many computer applications perform trigonometric calculations automatically, all the staff working in these industries will have an excellent knowledge of trigonometry and use it regularly.
Nurture Students’ Transferable Skills
Even if students do not wish to pursue a career in these technical and scientific fields, practicing trigonometry questions helps them develop transferable skills valued by all employers.
Using Trigonometry improves students’ problem solving abilities and promotes critical thinking, skills which will prove useful throughout their studies and into adult life. Providing students with trigonometry worksheets helps to nurture these skills, allowing them to be successful not just at their maths exams but right the way through their career.

Unit 1: Right triangles & trigonometry
About this unit.
Can you find the length of a missing side of a right triangle? You most likely can: if you are given two side lengths you can use the Pythagorean Theorem to find the third one. But, what if you are only given one side? Impossible? Cue sine, cosine, and tangent, which will help you solve for any side or any angle of a right triangle.
