what i'm lokkin for is that the linesegment Ab on triangele what is it.......

the median, altitude both?

Answer 1

Picture is too small.

Answer 2

From Wikipedia, here is the definition of altitude....
In geometry, an altitude of a triangle is a straight line through a vertex and perpendicular to (i.e. forming a right angle with) the opposite side or an extension of the opposite side. The intersection between the (extended) side and the altitude is called the foot of the altitude. This opposite side is called the base of the altitude. The length of the altitude is the distance between the base and the vertex.

So by this definition, I do believe it is an altitude.

Here, according to wikipedia is the definition of median of a triangle...

A median of a triangle is a straight line through a vertex and the midpoint of the opposite side, and divides the triangle into two equal areas. The three medians intersect in a single point, the triangle's centroid. This is also the triangle's center of gravity: if the triangle were made out of wood, say, you could balance it on its centroid, or on any line through the centroid. The centroid cuts every median in the ratio 2:1, i.e. the distance between a vertex and the centroid is twice as large as the distance between the centroid and the midpoint of the opposite side.

So, according to this definition, it is also the median of the triangle.

Answer 3

umm, what formula do you want?

For the sides AC or AD you use the pythagorean formula
AB^2 + BC^2 = AC^2. Since the triangle is symmetrical both side AC and AD can be solved like this.

To get the angles, theres a whole bunch of rules like the cosine law, sine law, etc. That you can use depending on what information your given.

Again I don't know what your actually asking for so this could all be irrelevant...

Answer 4

umm Pythagoras Theorem?
yes it is the altitude of the right triangle and it is also the median as it bisects the third side.
