What is a right triangle?
A right triangle (American English) is a triangle that has one right angle (90°). It is also known as a right-angled triangle (British English), or more formally, an orthogonal triangle.
Example of a right triangle
What is triangle calculator?
Triangles are one of the most basic shapes in geometry, and they're often used to explain more complicated shapes. Using a triangle calculator, you can easily calculate the dimensions of triangles and other basic math problems. This simple tool can be helpful when you're working on homework or trying to understand a more complex problem.
Pythagorean theorem
the Pythagorean theorem, also known as Pythagora's theorem, relates the three sides of a right triangle. According to this formula, the area of the square of a square whose side is the hypotenuse of a triangle is equal to the sum of the areas on the two other sides.
See the visual demonstration below:
Pythagorean theorem
Formulas of the right triangle
The right triangle has many useful formulas to utilize. You can use any of the formulas below to calculate the angles, sides, area, or perimeter of the right triangle. We will reference the triangle below for the following formulas:
Pythagorean Theorem
a^2+ b^2=c^2
Trigonometric functions
sin A = a / c
cos A = b / c
tan A = a / b
sin B = b / c
cos B = a / c
tan B = b / a
The area of a triangle
Area = a \* b / 2
The perimeter of a triangle
Perimeter = a + b + c
Also, note that you will need the table below when making use of the trigonometric functions:
For example, if you are using the tan B formula and calculating its value to be 1, then by looking at the table above, you will know that the value of the angle in question is to be 45°.
Daily life examples of the right triangle
The right triangle has many relevant and valuable formulas that are used in mathematics and real life. Below you will see three of the most important uses of the right triangle:
1) Architecture and engineering
It is not too far off to think about the usage of the right triangle in architecture. It is mainly used to calculate the length of the diagonal connection that connects two lines. This is used to calculate the diagonal length of a roof's slope when designing a sloped roof. You would only need to know the height and length of the roof, and you're good to go!
2) Electronics and electrical engineering
The right triangle is used for resolving math problems in electronics and electrical engineering, primarily when designing a model. Another example of the importance is when making aesthetic additions and making sure they don't disturb the function of the model.
However, the right triangle comes in very handy when working with circuits. See the below visual example for further demonstration and to understand how the right triangle logic translates into circuit logic.
3) Land surveying (civil engineering)
Surveying has been a profession that has been around for a long time, at least as long as recorded history shows. This is done by a surveyor who has the job of accurately measuring the earth's surfaces on a large scale. You might have guessed the use of the right triangle by now; basically, it comes in when the surveyor needs to calculate the length, areas, and relative angles between the objects on the landscape.
The example below is an excellent visual demonstrator of what has been previously explained. A surveyor uses relevant formulas to calculate his/her distance from the mountain top or from anywhere else they pick.
See the article below for further information on how surveying works:
