0. A right triangle, by definition, will never include any obtuse angles.
A triangle can never have three right angles
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
The sum of any two angles - whether one of them is a right angle or not - must be less than 180 degrees, since the sum of all three angles is 180 degrees.the sum of the measures of any two non-right angles in a right triangle equals 90 degrees.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
No right triangle can have any obtuse angles inside it.
A right angled triangle can have two 45° angles if it is isoceles
No
No
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
Any triangle that is not a right angle triangle
The interior angles of a triangle add to 180 degrees. This is true for any triangle, whether it is obtuse angled, right angles or acute.
No triangle has any 90-degree angles unless it's a right triangle. Most triangles are not.
The sum of the interior angles of ANY triangle is 180 degrees.
0. A right triangle, by definition, will never include any obtuse angles.
As with any triangle, inside the triangle.
