**Who was the first person to use the Pythagorean Theorem?**

So a is the length of the side opposite angle A. Using this notation we can succinctly state Pythagoras’ theorem and two of the most important theorems in trigonometry, the sine rule and the cosine rule. The sine rule and cosine rule are established in the Links Forward section. return to top. Right-angled triangles. Among the set of all triangles there is a special class known as right... Your aim is to find sets of three squares, which make a right angle triangle inside (There are only 5 to find). Use the set square to test if the largest angle is

**SOLUTION How do you calculate angles using pythagoras theorem**

The Pythagorean Theorem provides a relationship between the measures of the three sides of a right triangle. To show the relationship between the measure of the sides of a right triangle and the two acute angles of the triangle, you need to use the sine, cosine, and tangent trigonometric functions.... Remember that a 90 degree angle is called a "right angle." So, a rectangle has four right angles. So, a rectangle has four right angles. Opposite angles of a rectangle are congruent.

If you want Pythagorean triangles with a specific ratio of sides, e.g. 1 / 3, then use a function to find angle with a given sine or cosine or tangent. These are called the inverse trigonometric functions arcsine, arccosine and arctangent often abbreviated to asin, acos and atan and, given the since, cosine or tangent find the associated angle as a small positive number.

### Pythagoras' theorem states that for any right angle triangle that the square of its hypotenuse is equal to the sum of its squared sides or a^2 + b^2 = c^2 whereas …

- We have two responses for you. Hi, The height can be anything from 16 inches. to a height of almost zero. If the triangle is a right triangle as in the first diagram but it is the hypotenuse that has length 16 inches then you can use Pythagoras' theorem to find the length of the third side which, in this case, is …
- Or if you have two sides, then you can find the other side using the Pythagorean theorem. If you have an angle besides the right angle and a side then you can use the ratios of the trigonometric functions to find the other sides.
- 22/01/2007 · Using the Pythagorean theorem we would find: Solving for C would produce a hypotenuse of 9.2195444 feet – which would be very difficult to calculate mentally or locate on a tape-measure that is graduated in 8ths or 16ths of an inch.
- Finding Missing Angles . Home > How To Find Missing Angles; The three examples below show how angle relationships and the properties of triangles can be used to find unknown angles.
