Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
no
No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.

there are eight right angled triangles
No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.

Right triangles can have only one line of symmetry. Only right triangles with two 45 degree angles can have a line of symmetry.
