All triangles have a height because the area of any triangle is 0.5*base*perpendicular height
Parallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*Height
Simple. Just multiply the base by the height of the triangle, and divide it into two. This works for all types of triangles.
You will use what you know about the triangle, including the size of sides or angles of that specific triangle, plus properties of any special category of triangles of which it is a member, to calculate the unknown height.
No, a triangles area is calculated from base x height / 2

It depends on the triangle. There is no description of this relationship that fits all triangles.

I suppose by "length of a triangles altitude" you mean height. The height of the triangle in question cannot be determined from the information given. In order to determine the height of the triangle, two dimensions must be known.

Triangles don't have a diameter. They have a base and a height.

For all triangles: area = 1/2 * base * height
# The triangles are congruent, therefore triangle 1 has the same angles and lengths as triangle 2 # The triangles are isosceles, therefore two of the sides are the same length, and two of the angles are the same # The triangles are right, therefore the angle between base and height is 90 degrees Applying 2, and 3: A triangle that is both isosceles and right has the angles 45, 90, 45 degrees and the lengths base = height = hypotenuse / sqrt(2) Applying 1: Therefore, the triangles can share their base and heights with each other freely, but their hypotenuse can only be shared with each others hypotenuse. * If Triangle-1 shared it's hypotenuse with triangle-2's base, or height which are not the same size, the resulting shape would have five sides which is not a quadrilateral. So... # If triangle-1 shares its base with triangle-2's base, or if triangle 1 shares its height with triangle's 2 height, you are left with an equilateral triangle # If triangle-1 share its base with triangle-2's height, or if triangle 1 share its height with triangle's 2 base you are left with a trapezoid # If the triangles share a hypotenuse, you are left with a rectangle in which base = height. Otherwise known as a square There are three different types of quadrilaterals that can be made.
The first is clearly not a suitable triangle.
Basically, triangles have 3 bases. Unless you want to calculate the area of the triangle(which requires the height), triangles have three bases.
