# Right Triangle Calculator: What is a Right Angled Triangle, and how to conclude it?

Welcome to **Allcalculator.net**, your reliable source for a wide range of financial tools and calculators. Make use of our intuitive **Right Triangle Calculator**, designed to help you determine whether a triangle is a right-angled triangle. With our calculator, you can conveniently measure the sides and angles of the triangle to verify its right-angled nature. Trust Allcalculator.net to provide you with accurate calculations and instant results, ensuring you have the right information about your triangle's properties.

So in a Right Angled Triangle, one angle measures 90°. The reason why this Triangle is called a Right Angled Triangle. The all the angles in the Triangle should add up to make it 180°. So if one of the interior angles measures 90°, it is obvious the other two angles will be either 45° or 30° and 60° respectively.

So in a right-angled Triangle, the complementary angles must be less than 90°meaning acute angles.

So let's assume

α+β+90(as one angle measures 90°l)=180(sum of all Angles)

α+β=180-90

α+β=90

Here α and β are the other two complimentary angles in the Triangle. The values of these angles are unknown.

The Right Angle Triangle should also meet all the **Pythagorean Theorem** rules. It means the Triangle should have a long side, and it is the hypotenuse of that Triangle. The other two sides in the triangle need to be equal.

**C=√a^2+b^2**

Here a and b are the two sides of a triangle. Also, it should meet all the trigonometric rules if the Triangle meets all these requirements.

### How to Conclude if a Triangle is a Right Angle Triangle with the Calculator?

Now let's understand how To conclude if it is a Right Angled triangle.

Check the Triangle in each aspect and parameter of the Triangle you are calculating while using our Right Angled Triangle Calculator.

- Pick any given parameters if it's the three sides, angles α and β or two equal sides and one hypotenuse. Also, at an angle, one should be 90°.
- If you choose two sides and one angle, you can use the option in the Calculator to determine the remaining values.
- Input the values you know for quick Calculation.

Once you input all these values into the Calculator, the Calculator will quickly list the results if the Triangle is a **Right Angled Triangle** or not.

### Conclusion

The Right Angled Triangle will conclude the results based on the inputs provided. It will also give the missing angles' values and sides and determine if it's a right-angled Triangle.
