Each side is: 66.6/3 = 22.2 cm
Its area is: 0.5*22.2*22.2*sin(60 degrees) = 213.40598 square cm

Kinds of triangles according to sides?
A scalene triangle has no sides of equal length.An isosceles triangle has two sides of equal length.An equilateral triangle has all three sides of equal length.
What is the perimeter of an equilateral triangle whose sides measures 8.5 meters?
An Equilateral Triangle has 3 equal sides so 3 X 8.5m = 25.5m
What are the differences between a triangle and an octagon?
Triangle has 3 sides, 3 vertices (corners) whose interior angles add up to 180. Octagon has 8 sides, 8 vertices, whose interior angles add up to 1080 degrees. A regular triangle (all sides equal, all angles equal), has interior angles of 60 degrees. A regular octagon (all sides equal all angles equal), has interior angles of 135.
A triangle whose sides are all congruent?
An equilateral triangle.
Example of scalene triangle?
A triangle with side lengths 1, 2, square root(3). A scalene triangle is any triangle whose sides are all of different lengths. It may or may not have a right-angle. Compare with isosceles triangles (2 out of 3 sides are equal in length) and equilateral triangles (all 3 sides are equal in length).
What is an equal triangle?
An equilateral triangle is a triangle whose three sides are equal.
What is an equallity?
An equilateral triangle is a triangle whose three sides are equal.
What triangle has 3 equal sides and 3 equal angels?
By definition, an equilateral triangle, which is a triangle whose sides are equals and each of its angles has 60º.
Kinds of triangles according to sides?
A scalene triangle has no sides of equal length.An isosceles triangle has two sides of equal length.An equilateral triangle has all three sides of equal length.
What adjective describes a triangle whose sides are equal?
equilateral
What is a equalateral triangle?
It is a triangle whose 3 sides are equal in length and its 3 interior angles each measure 60 degrees
What is equelatiral triangle?
If equelatiral is meant to be equilateral, then it is a triangle whose three sides are of equal length.
What is the perimeter of an equilateral triangle whose sides measures 8.5 meters?
An Equilateral Triangle has 3 equal sides so 3 X 8.5m = 25.5m
What are the differences between a triangle and an octagon?
Triangle has 3 sides, 3 vertices (corners) whose interior angles add up to 180. Octagon has 8 sides, 8 vertices, whose interior angles add up to 1080 degrees. A regular triangle (all sides equal, all angles equal), has interior angles of 60 degrees. A regular octagon (all sides equal all angles equal), has interior angles of 135.
Write a statement that must be true about an equilateral triangle and an isosceles triangle?
An equilateral triangle is also isosceles.Improved Answer:-They are both triangles whose 3 interior angles add up to 180 degrees and an equilateral triangle has 3 equal angles with 3 equal sides whereas an isosceles triangle has 2 equal angles with 2 equal sides
A triangle whose sides are congruent?
An equilateral triangle
How can an isosceles triangle be an equilateral triangle?
An isosceles triangle can never be an equilateral triangle because only 2 of its 3 sides are equal in lenght whereas an equilateral triangle has all 3 of its sides equal in length. But an isosceles triangle can take the shape of a right angle triangle whose interior angles are 90, 45 and 45 degrees.
