Altitude of a triangle
Description
The altitude of a triangle is the distance from a vertex perpendicular to the opposite side. There is a relation between the altitude and the sides of the triangle, using the term of semiperimeter too.
( The semiperimeter of a triangle is half its perimeter.)
Variables
| h | Altitude to side a (m) |
| a | Side corresponding to altitude h (m) |
| s | semiperimeter (m) |
| b | side of the triangle (m) |
