- The ratio of the length of the side opposite a given angle to the hypotenuse is the sine of that angle.
- The ratio of the length of the side adjacent to a given angle to the hypotenuse is the cosine of that angle.
- The ratio of the length of the side opposite a given angle to the side adjacent to that angle is the tangent of that angle.

What traingle don't have a right angle?
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
Are all right triangles isosceles triangles?
no
Are some right triangles are also equilateral triangles?
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.
Can all 4 sided shape be made by two right angled 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.
Are some right triangles have equilateral triangles?
No. For it to be equilateral it can't be a right triangle.
Do all triangles have right angles?
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.
Which triangles have a right angle?
Right angled triangles!
