Students graph and identify the properties of trigonometric graphs. They differentiate between sine, cosine and tangent graphs. They define the parts of the formulas and how they affect the graphs.
Learners determine the trigonometric relationships within a triangle as they construct a right triangle on the Ti-89. They find the sine, cosine, and tangent of various angles of their triangle construction.
Learners solve problems using trigonometric functions, specifically a problem about a tree stand. Pupils try to maximize the distance of hunting sight given certain restrictions. They use the Pythagorean Theorem, sine, cosine, and tangent to determine the best placement of a tree stand on a tree.
In this math worksheet, 10th graders solve problems involving a tangent line intersection the arc and forming various angles. There are 6 problems to be solved.
For this geometry worksheet, 10th graders review the formulas and theorems on circles.  Problems are comprehensive and detailed.  The worksheet is eleven pages long and contains nine problems.   Not all answers are included. 
Explore lines tangent to a circle. In this math lesson, high schoolers manipulate circles and lines on a TI calculator. They draw a circle  and analyze perpendicular lines intersecting the circle in only one place. This activity works best if each student has a TI-83 or TI-84 for their own viewing.
In this circles review worksheet, students complete 12 problems involving missing lengths of circles. Students then complete an associated mystery phrase.
In this parts of a circle worksheet, students place the names of 6 different parts of a circle in rectangular place holders. They use labels such as cord, secant, diameter, radius, tangent, and center.
High schoolers watch a video of real-world situations regarding speed, direction, velocity, force, etc. and answer questions while viewing. They then practice drawing and using vectors to solve more real-world problems.
Young scholars create posters.  In this concepts lesson, groups of students use the internet to research different proofs of the Pythagorean Theorem.  In addition, they research Greek Mathmaticians.  Young scholars create posters and bulletin boards containing their information. 
Investigate and differentiate between a variety of geometric construction using TI-Nspire. In this math lesson, students construct lines, circles, triangles and squares then compare and contrast these constructions.       
Young scholars identify the different angles using the properties of trigonometry. In this trigonometry lesson, students find the coordinates of the terminal side of an angle in standard position.
Students calculate the third quantities. In this trigonometric instructional activity,students are given information about the arc length and angle or radius and asked to find the radius or arc length. They use the unit circle to help find their answers.
In this geometric mean and Pythagorean Theorem worksheet, 10th graders solve 94 various types of problems related to determining the geometric mean and using the Pythagorean Theorem to measure triangles. They find the indicated trigonometric ratio as a fraction and as a decimal rounded to the nearest ten-thousandth. Students also draw a given triangle and write an equation to use to find the unknown values.
Students investigate and use the unit circle. In this trigonometry lesson plan, students apply the ratios of trig functions to identifying the different angles represented by the unit circle. The play a game to reinforce this knowledge.
Students identify and investigate trigonometric functions. They practice the correct way to write trigonometric and inverse ratios. They graph and identify the different parts of a trig function.
Students determine measurements and distances using trigonometric ratios. In this astronomy lesson students demonstrate the difference between a positive and negative slope using the Pythagorean Theorem.
Students study the islamic achievement in mathematics In this algebra lesson, students review the six forms of equations of Al-Khwarizmi. They solve equations using different forms.
For this geometry worksheet, 10th graders use a graphing calculator to evaluate trigonometric functions and their inverses. The four page worksheet contains explanation, examples, and twenty questions. Answers are not included.
Students identify the six trigonometric ratios and properties. In this trig lesson plan, students define basic trig functions as it relates to solving right triangles. They identify the equation for sine as o/h and cosine as a/h and tangent as o/a.
