In a right-angled triangle: o the side opposite the right angle is called the hypotenuse o the side opposite the angle θ is called the opposite o the side next ...

Many people are more familiar with a degree measurement of an angle. Below is a quick formula for converting between degrees and radians.

We will now learn to use the three basic trigonometric ratios to find missing angles of right triangles. Tutorial: For a more detailed exploration of this ...

In a right-angled triangle the side opposite the right angle is called the hypotenuse. The hypotenuse is always the longest side. Pythagoras' theorem is used to ...

In this section, we are interested in using trigonometric functions to compute the values of all angles and sides of any right triangle, given the value of ...

Right-angled trigonometry allows you to find a missing angle or side in a right-angled triangle when given two sides, or an angle and a side.

Trigonometry allows us to find missing sides and angles in right-angled triangles. It uses the sine, cosine and tangent ratios. These are special ratios ...

You can use a calculator to find the measure of an angle when you know the value of the sine, cosine, or tangent of the angle. Use the inverse sine, inverse ...

Pythagoras' Theorem relates the length of the hypotenuse of a right-angled triangle to the lengths of the other two sides. The hypotenuse is always the longest ...

Two right angled triangles, A and B, are joined together to form a new triangle. The longest side of triangle A is 10 m and the angle between the height of ...
