Every angle of a square is a right angle, because they're all 90o.
Neither because the 4 angles inside a square are all right angles.
acute
A square is a rectangle and a rectangle MEANS 90 DEGREES, so a square also has 90 degrees. :P
A square is a special case of rhombus, where all angles are equal to 90°. So if it's not a square, then the rhombus will have 2 acute angles and 2 obtuse angles.
right
A square
No. Just 4 right-angles
They will be acute angles.
They are neither, they are all right angles (90 degrees)
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
acute and obtuse.
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
