No because an equilateral triangles has 3 equal sides and 3 equal angles of 60 degrees.
But there is such a thing as an isosceles right angle triangle which has 2 equal sides and a 90 degree angle with two equal angles of 45 degrees.

No isosceles triangle in the world is congruent to any equilateral triangle. No equilateral triangle in the world is congruent to any right triangle.
Only right triangles have right angles. An equilateral triangle though can't have a right angle because all the angles in any type of triangle must add up to 180 degrees. For each angle to be equilateral, they must be 60 degrees, showing that there is no angle at 90 degrees in an equilateral triangle, which would signify that it would be right.
No, they are all 60 degrees
No. It has 3 angles of 60° each.
Any triangle that is not isosceles or equilateral. An equilateral triangle has 3 lines of symmetry, while an isosceles triangle has only one, and any other triangle (non-isosceles right triangle, or scalene triangle) has zero.
