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.
Yes, an isosceles triangle can have an obtuse interior angle. An isosceles triangle has at least two equal sides and can have one angle greater than 90 degrees, making it obtuse. In such a case, the two equal angles would be acute, ensuring that the sum of the interior angles still equals 180 degrees.
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.
