A triangle can have only one right angle (90o). Such a triangle is called a right triangle.
There is one 90 degree angle in a right angle triangle
An obtuse triangle is a triangle that has one angle greater than 90 degrees.
The sum of all angles in any triangle is 180o The largest angle in aright angle triangle is 90o
There can be 6 right angle triangles
there are three angles on an isosceles triangle
A right-angle triangle will have one right-angle (90 degrees).
Sum of all angles at vertices in a triangle is 180. Right angle means 90 Degree. A triangle can have only one Right angle.

The only diagonal line in a right-angle triangle is the hypotenuse. So the answer is 1.
