angles that measure 90 degrees.
An acute angled triangle, right angled triangle or obtuse angled triangle.
An obtuse angled triangle is wider than a right angled triangle. It has 180 degree angles.
a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
The sum of the interior angles of any triangle is 180 degrees. Whether or not it is right angled is irrelevant.
Any of the above: you can have a right-angled isosceles (not isoscles!) triangle, or an obtuse-angled one or an acute angled-one.
An acute angled triangle, right angled triangle or obtuse angled triangle.
No a right angled triangle consists of two acute angles and one right angle
It has 3 angles
An obtuse angled triangle is wider than a right angled triangle. It has 180 degree angles.
a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
A right-angled triangle is one which has, as one of the angles, an angle of exactly 90 degrees.
The sum of the interior angles of any triangle is 180 degrees. Whether or not it is right angled is irrelevant.
A right angled triangle can only have two acute angles.
Any of the above: you can have a right-angled isosceles (not isoscles!) triangle, or an obtuse-angled one or an acute angled-one.
