Not necessarily. Rectangles are quadrilaterals and have no acute angles.
Yes. Rectangles have four right angles.
Any polygon can contain acute interior angles.
Any shape with 4 acute angles must have more than 4 sides. Any shape with more than 4 sides can have 4 acute angles (but doesn't have to).
Just about any shape that isn't a circle can have two or more acute angles. But with some of them, you need to make them have acute angles.
Not necessarily. Rectangles are quadrilaterals and have no acute angles.
Yes. Rectangles have four right angles.
A decagon can have acute angles.
Yes. A rectangle is a parallelogram that has right angles instead of acute and oblique angles at the corners. But not all parallelograms are rectangles.
Obtuse angles are no more important than acute or right angles. The commonest tessellation uses squares (or rectangles) and these have right angles - not obtuse.
You can't, it's impossible since rectangles have all right angles.
Any polygon can contain acute interior angles.
A square and a rectangle have opposite equal 90 degree angles. A parallelogram and a rhombus have 2 opposite equal acute angles and 2 opposite equal obtuse angles.
Any shape with 4 acute angles must have more than 4 sides. Any shape with more than 4 sides can have 4 acute angles (but doesn't have to).
Just about any shape that isn't a circle can have two or more acute angles. But with some of them, you need to make them have acute angles.
They are both 4 sided quadrilaterals but a rectangle has 4 right angles whereas a parallelogram has 2 equal opposite acute angles and 2 equal opposite obtuse angles.
No its a obtuse line there are no acute lines in it
