Triangle Angle Calculator
Calculate angles in triangles easily with our online tool.
What is the Triangle Angle Calculator & How does it work?
A triangle is a polygon with three sides and three angles. The sum of the interior angles of any triangle is always 180 degrees.
To calculate an unknown angle in a triangle, you can use the fact that the sum of all angles must equal 180 degrees. If two angles are known, the third can be found by subtracting the sum of the known angles from 180.

theta_3 = 180 – (theta_1 + theta_2)
theta_3 = Third angle, theta_1 and theta_2 are known angles

Third Angle (Β°)β
Frequently Asked Questions
How do I find the missing angle in a triangle?
To find the missing angle, subtract the sum of the two known angles from 180 degrees.
What is the formula for calculating a triangle’s third angle?
The formula is ΞΈ3 = 180 – (ΞΈ1 + ΞΈ2), where ΞΈ1 and ΞΈ2 are the known angles.
Can this calculator handle any type of triangle?
Yes, it works for all types of triangles as long as you know two of the three angles.
What if I only know one angle? Can I still use this calculator?
No, you need at least two known angles to calculate the third using this method.
Is there a maximum or minimum value for the angles in a triangle?
The sum of all three angles must be exactly 180 degrees, and each angle must be between 0 and 180 degrees.
Can this calculator help with right triangles?
Yes, it can calculate the third angle in a right triangle if you know the other two angles.
Does this tool work for obtuse or acute triangles?
Yes, it works for both obtuse and acute triangles as long as you provide the correct two known angles.
