No. A square must have four 90 degree interior angles, or else it is not a square.
An obtuse angle is greater than a square angle. A square or a rectangle both have 4 interior right angles
a triangle that contains an obtuse interior angle
Yes, it can.
In a regular 8 sided octagon each interior angle is 135 degrees which is an obtuse angle
NO, a square had only four right angle (90 degree angles). An obtuse angle is any angle greater/larger than 90 degrees. So a square has NO obtuse angles at all.
There are no obtuse angles in a square. A square is a perfect 90 degree angle.
obtuse
Some have one obtuse interior angle, others have none. A triangle can have no more than one obtuse angle.
No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.
It can be an acute, right angle or an obtuse angle depending on its size.
No. By definition, a square can have only right angles.
Sometimes it has an obtuse angle. If it is just a parallelogram or a rhombus, then it has two obtuse angles.\. If it is also a rectangle or a square, then it has four right angles.
