## How to Find Triangle Properties Using our Triangle Calculator

**Input Your Values**- Enter**three values**, which can be a combination of sides and angles. Ensure they describe a valid triangle, it does not have to be a right triangle.**Review the Results**- Our calculator processes the inputs and displays all the triangle properties, such as; Triangle type, side lengths, angles, area, perimeter, semiperimeter, height, medians, inradius, and circumradius.**Find Your Answer**- Look for the triangle property you wanted to calculate in the results

### Tips for Accurate Results:

- Make sure you have 3 data values entered into the calcualtor above.
- Ensure the sum of angles does not exceed 180 degrees.
- At least one side must be entered.
- For side inputs, the sum of any two sides should be greater than the third.
- Double-check your inputs for any typographical errors.

## How to Calculate Each of These Triangle Properties on Your Own

### Triangle Type:

**By Angles**: You can classify triangles based on their angles as shown below.**Acute Triangle**: All angles are less than 90 degrees.**Right Triangle**: One angle is exactly 90 degrees.**Obtuse Triangle**: One angle is more than 90 degrees.

**By Sides**: You can classify triangles based on their sides as shown below.**Equilateral Triangle**: All sides are equal.**Isosceles Triangle**: Two sides are equal.**Scalene Triangle**: All sides are of different lengths.

### Side Lengths & Angles:

**Pythagorean Theorem**: Useful for finding the missing side of a right Triangle.For missing side use A^2 + B^2 = C^2 with C being the hypotenuse.

**Law of Cosines**: Useful for finding a side when two sides and an angle in-between are known, or an angle when all sides are known.**Law of Sines**: Useful when the lengths of two sides and a non-included angle are known, or two angles and any side.

### Area:

**Heron's Formula**: Use to find area when you know all three sides.**For Right-Angled Triangles**: Area = b*h / 2

### Perimeter & Semiperimeter:

**Perimeter**: Add up the lengths of all three sides.**Semiperimeter**: Half of the total perimeter, used in various formulas.

### Height:

- The height is the perpendicular distance from a vertex to the opposite side.
Use the area formula and solve for Height = 2*Area/base.

### Medians:

- A median connects a vertex to the midpoint of the opposite side.

### Inradius & Circumradius:

**Inradius**: The radius of the inscribed circle within the triangle.**Circumradius**: The radius of the circumscribed circle around the triangle.
