No
The sum of the angles in any triangle is 180. This includes Equalateral triangles.
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.
No
A right angled triangle can have two 45° angles if it is isoceles
Any triangle that is not a right angle triangle
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
No triangle has any 90-degree angles unless it's a right triangle. Most triangles are not.
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.
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.
