If it's a scalene then yes. one. otherwise no.
Except an isosceles triangle can also have a right angle between the sides of equal length; the equal angles then being 45o each.
A triangle can have at most one right angle.
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.
No, an equilateral triangle does not have right angles. All three interior angles of an equilateral triangle are equal and measure 60 degrees each. Since right angles measure 90 degrees, an equilateral triangle cannot contain any right angles.
