The right-angled triangle is a special kind of triangle, with one angle being 90 degrees (right angle), which is very common in daily life. There are two methods to calculate the area of a right-angled triangle, namely the calculation method based on the lengths of the two right-angled sides and the calculation method based on the base and height. This article introduces in detail these two methods for calculating the area of a right-angled triangle.
- The method of calculating based on the lengths of the right-angled sides
Using the method of calculating based on the lengths of the right-angled sides, the formula for the area of a right-angled triangle is: S = 1/2 * a * b, where a and b represent the lengths of the two right-angled sides respectively.
- The method of calculating based on the base and height
Using the method of calculating based on the base and height, the formula for the area of a right-angled triangle is: S = 1/2 * a * h, where a represents the length of the hypotenuse, and h represents the height on the hypotenuse.
The characteristic of this formula is that the area can be calculated by knowing only the length of the hypotenuse and the height on the hypotenuse.
The right-angled triangle is also a type of triangle, and its area can be calculated completely according to the traditional base-by-height formula. Refer to “Triangle Area Formula”.
The knowledge points that need to be paid attention to include: “Triangle Area Formula”, “Right-angled Triangle Area Formula”, “Equilateral Triangle Area Formula”, “Hyperbola Focus Triangle Area Formula”, and “Ellipse Focus Triangle Area Formula”.
