Right Angles and Trigonometric Values

Is it possible to be the same yet different? Absolutely! The activity asks learners to explore the relationships between side ratios of triangles they have drawn. Because individuals all draw a triangle with the same angle measures, they...

Practice manipulating trigonometric functions, cofunctions, inverses, and applications is the name of the game in this short but extensive problem set. Starting with the Pythagorean Theorem and basic applications, then progressing...

In this right triangle trigonometry worksheet, students find the measure of specified angles. Students determine the length of the missing side of a right triangle. This four-page worksheet contains 24 problems. Answers to the worksheet...

Right triangles are so special! Use special right triangles to discover the trigonometric ratios. Pairs construct special right triangles and find the values of the ratios of the sides. In the process, they discover the ratios stay the...

In this trigonometric ratio worksheet, students determine the length of a side of a right triangle, or the measurement of angles using trigonometric ratios. This one-page worksheet contains 24 problems. Answers are provided at the bottom...

In this right triangle worksheet, students use trigonometric ratios to find the missing measurement of right triangles. This nine-page worksheet contains 10 multi-step problems. Answers are provided at the end of the worksheet.

Right you are to use a great resource. Starting with a lesson on dilations, scholars learn about similarity transformations and similar triangles. They use the knowledge to develop an understanding of right triangle trigonometry in later...

Using trigonometric ratios to solve geometry and application problems is the focus of this detailed problem set and solution presentation. The presentation covers many ways to use trigonometry, from finding missing measures in right...

The more you know, the more you can learn. Scholars apply the double angle and half angle formulas to determine trig values based on known values. They use an interactive that provides sine and cosine values to aid calculations.

It's important to be exact. Scholars watch a video that provides the exact trigonometric values of sine, cosine, and tangent for 0-, 30-, 45-, 60-, and 90-degree angles. The video also highlights a pattern to help remember the values.
