The altitudes of a triangle are the lines that pass through the vertex of the triangle and are perpendicular to the opposite side. The orthocentre is an important point in triangle geometry and plays a crucial role in several theorems and properties of triangles.
Orthoceras
Orthoceras is an extinct genus of cephalopods, a type of marine animal related to squids and octopuses. The name "orthoceras" comes from the Greek words "orthos," meaning "straight," and "keras," meaning "horn." This refers to the distinctive straight, horn-like shape of the fossilized shells of these creatures, which are often found in sedimentary rocks dating back to the Silurian and Devonian periods, around 440-360 million years ago.

Orthochromatic film is often used in scientific and technical applications, such as in the study of minerals and rocks, because it can help to enhance the contrast and visibility of certain features. It is also used in some artistic applications, such as in black and white photography, where it can be used to create distinctive and stylized images.
