Use this right triangle area calculator to quickly calculate area of right triangle using the base and height. The tool demonstrates the right triangle area formula.
A = area of right triangle
base = one perpendicular side
height = other perpendicular side
The right triangle area formula multiplies the two perpendicular sides and divides by 2.
| Base | Height | Area |
|---|---|---|
| 3 | 4 | 6 |
| 5 | 12 | 30 |
| 6 | 8 | 24 |
| 7 | 24 | 84 |
| 9 | 12 | 54 |
To manually calculate area of right triangle:
1. Measure the two perpendicular sides (base and height).
2. Multiply the base by the height.
3. Divide the result by 2.
4. The result is the area.
This right triangle area calculator instantly calculates the area using the right triangle area formula with six decimal places accuracy. Useful for students, teachers, and engineers.
• Right triangles are fundamental in trigonometry.
• The Pythagorean theorem applies to right triangles.
• The area formula only requires the two perpendicular sides.
• Right triangles are used in construction and architecture.
• Special right triangles like 3-4-5 are widely used in engineering.
