Calculadora de Ángulos del Triángulo Gratis
Calcula el tercer ángulo de un triángulo conociendo los otros dos. La suma de ángulos siempre es 180°.
Angle C
50.00 degrees
Fórmula
## How to Find a Missing Triangle Angle ### Formula **Angle C = 180° - Angle A - Angle B** The sum of all interior angles of a triangle is always 180 degrees. If you know two angles, you can find the third by subtracting their sum from 180. ### Triangle Types by Angles - **Acute**: All angles less than 90° - **Right**: One angle exactly 90° - **Obtuse**: One angle greater than 90°
Ejemplo Resuelto
A triangle has angles of 60° and 70°. Find the third angle.
- 01Angle C = 180° - 60° - 70°
- 02= 180° - 130°
- 03= 50°
Preguntas Frecuentes
Why do triangle angles add up to 180 degrees?
This is a fundamental property of Euclidean geometry. It can be proven by drawing a line parallel to one side through the opposite vertex and using alternate interior angles.
Can a triangle have two right angles?
No. Two right angles would sum to 180°, leaving 0° for the third angle, which is impossible. A triangle can have at most one right angle or one obtuse angle.
