A triangle can be rotated through any angle of your choice!An equilateral triangle has rotational symmetry of order 3, which means that a rotation of 120 degrees (or multiples) will bring it back to the same orientation. All other triangles have rotational symmetry of order 1: that is, you have to rotate them a full circle (360 deg) before they look the same.
Yes. Any triangle can be inscribed in a circle.
Yes and perfectly
You will need... A set of compasses (for drawing the circle), and a straight edge. First, draw the circle. Then - put the point of the the compasses on the line. Mark the circle where the pencil crosses it. Place the point on this intersection and repeat the action until you're back at your starting point. Now - using the straight edge, join every alternate point to each other - forming an equilateral triangle.
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°

An equilateral triangle inscribed in a circle has three sides that are equal in length and three angles that are each 60 degrees. The center of the circle is also the intersection point of the triangle's perpendicular bisectors.
Where the side of the equilateral triangle is s and the radius of the inscribed circle is r:s = 2r * tan 30° = 48.50 cm
