It depends on what else you know about the triangle.
The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.
There can be no tangent side. The tangent of an angle, in a right angled triangle, is a ratio of the lengths of two sides.
In a right angled triangle its hypotenuse when squared is equal to the sum of its squared sides which is Pythagoras' theorem for a right angle triangle.
1/2*base of triangle*height(the perpendicular)=Area of right angled triangle
Pythagoras's' theorem or "got an want" on a right angled triangle but use sine rule on a non right angled triangle !! ..
The right-angled triangle.
A right angle triangle
A right(-angled) triangle
All triangles have 180o. A right-angled triangle has one right angle. A right angle is 90o.
a right angled triangle is special because it is the only triangle that has a right angle with a dregree of 180.

It is a right triangle or right-angled triangle. The right-angle is 90 degrees.
Right angled triangle.
A right-angled triangle is one which has, as one of the angles, an angle of exactly 90 degrees.
Exactly as in the question it is a right angle triangle
A right angled isosceles triangle!
A right (angled) triangle.
