Parameters

Description

Examples

Calling Sequence

medial(mT, T, n)

Parameters

mT

-

the medial triangle to be created

T

-

triangle

n

-

(optional) a list of three names denoting the names of three vertices of the medial triangle

Description

• 

The medial triangle mT of triangle T is the triangle formed by joining the midpoints of the sides of triangle T.

• 

If the optional argument is given and is a list of three names, these three names will be assigned to the three vertices of the medial triangle mT

• 

For a detailed description of the medial triangle mT, use the routine detail (i.e., detail(mT))

• 

Note that the routine only works if the vertices of triangle T are known.

• 

The command with(geometry,medial) allows the use of the abbreviated form of this command.
