Oblique Triangle Calculator

How to use the Oblique Triangle Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

angleA_1=one_way(acos((c_1^2+b_1^2-a_1^2)/(2×c_1×b_1)))

angleB_1=one_way(acos((a_1^2+c_1^2-b_1^2)/(2×a_1×c_1)))

angleC_1=one_way(acos((a_1^2+b_1^2-c_1^2)/(2×a_1×b_1)))

s_1=one_way((a_1+b_1+c_1)/2)

area_1=one_way(sqrt(s_1×(s_1-a_1)×(s_1-b_1)×(s_1-c_1)))

c_2=one_way(sqrt(a_2^2+b_2^2-2×a_2×b_2×cos(angleC_2)))

The calculator uses 13 further relationships to link its other values.

Frequently asked questions

What is an oblique triangle?

An oblique triangle is a triangle that does not contain a right angle (90 degrees). It can be classified into two types: acute triangles, where all angles are less than 90 degrees, and obtuse triangles, where one angle is greater than 90 degrees.

How do I use the oblique triangle calculator?

To use the oblique triangle calculator, simply input the known parameters, such as two sides and the included angle (SAS), or the three sides (SSS). The calculator will use the law of sines and law of cosines to find the remaining angles and sides of the triangle.

What formulas are used in the oblique triangle calculator?

The calculator utilizes various formulas, primarily the law of sines: (a/sin(A) = b/sin(B) = c/sin(C) and the law of cosines: c² = a² + b² – 2ab * cos(C) to calculate unknown sides and angles.

Is the oblique triangle calculator easy to use?

Yes, the oblique triangle calculator is designed to be user-friendly. It provides a straightforward interface for inputting values, and within seconds, it delivers accurate results, making it a perfect tool for both students and professionals.

Can the calculator solve all types of oblique triangles?

Yes, the oblique triangle calculator can solve both acute and obtuse triangles, as long as you provide the necessary information such as sides and angles. It can also handle cases where only two sides and a non-included angle are known.
