No
No because it only has a Right angle. It doesn't have an Obtuse angle, or other angles.
No because it can only contain a right angle and two acute angles
If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.
Some examples are: circle, square, rectangle, right angle triangle, equilateral triangle
No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees
-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
Yes . Triangle have right acute and obtuse angle except compelete angle.
No because the 3 interior angles of a triangle add up to 180 degrees
