What is the definition for leg of a triangle?
There is no formal definition: it is any side of a triangle. Often, if the triangle has a horizontal base, then it is one of the sloped sides. In a right angled triangle, it is one of sides adjacent to the right angle. In an isosceles triangle, it is one of the equal sides.
How do you find the area of a 3-dimensional triangle?
A triangle by definition only has 2 dimensions.
What is the definition of leg of an isosceles triangle?
It is one of the two equivalent sides on the isosceles triangle.
Is a triangle always a rhombus?
A rhombus by definition has four sides, and a triangle has only three. So, a triangle is never a rhombus.
If it is an equilateral triangle then it is an isosceles triangle?
Let us recall the definition of an isosceles triangle. An isosceles triangle is a triangle with two equal or congruent sides. In this definition, it is not stated that it has exactly two equal sides. An equilateral triangle has three equal or congruent sides. If it has three equal sides, then it must have two equal sides. Therefore, an equilateral triangle is considered as an isosceles triangle. But, an isosceles triangle is not necessarily an equilateral triangle.
