Weegy: how can i help you ? User: what is the sum of the interior angles of a triangle
User: An equilateral triangle is a Weegy: The area of any equilateral triangle always an irrational number.
The area of any triangle in square units is 2 bh where b is the base-length and h the perpendicular height of the apex from the base. We can find h by Pythagoras' theorem ... [ which equals 3/2. The area (?bh) is therefore equal to 3/4 square units. This irrational number results from applying a square peg to a triangular hole . The fit is awkward, complex, and dysfunctional.
Reference: ] User: An equilateral triangle is a rhombus
Weegy: When a Rhombus is cut in half, it will equal two equilaterial triangles. Thanks for asking Weegy! (More)
