triangle
No, a triangle is defined by its three sides and/or its angels. The diameter is a characteristic of a circle.
An obtuse triangle has an angle which is greater than 90 degrees.
A right triangle has a 90 degree angle, and an obtuse triangle has an angle greater than 90 degrees
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
There is no such thing as a milemeter. Assuming you meas millimetres, there is no answer possible because it will depend on the shape and size of the triangle as well as what characteristic of the triangle is being measured.
all equal -sides -angles =]
Any geometric shape that has more than three sides.
It depends on what the formula is for: the area or perimeter or some other characteristic.
These are some characteristics of equilateral triangle:All the sides of an equilateral triangle are equalIn an equilateral triangle each angle is angle is 60 degree.With an equilateral triangle, the radius of the incircle is exactly half the radius of the circumcircle.
The answer might just depend on what characteristic of the triangle is represented by x.
It is any triangle - one with no special characteristic - like a right angle, or two equal sides, etc.
