It can be proven that the sum of all the internal angles of a polygon with n sides is (n-2)*180 degrees.
In the case of a square, n = 4 and so the angles sum to (4-2)*180 = 2*180 = 360 degrees.

Are all angles of a parallelogram equal to 90 degrees?
No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).
Are the angles of a rhombus all equal?
A rhombus looks like a lopsided square, or a diamond shape. It is a parallelogram with four equal sides. The angles of a rhombus do not all need to be equal BUT opposite angles of a rhombus ARE equal. If you were to "straighten it up" and make all the angles equal at right angles, it would be a square. A rhombus with four right angles is a square.
What are the sizes of the other interior angles of a rhombus when one of them is 33 degrees?
It will have 2 opposite equal angles of 33 degrees and 2 opposite equal angles of 147 degrees
What quadrilateral has 2 sets of parallel sides of equal length?
A square has 3 sets of parallel sides of equal length AND all the angles are 90 degrees. A rhombus has 2 sets of parallel lines of equal length, but the angles aren't all 90 degrees.
What shape is a parallelogram with all angles equal to 90 degrees and it's diagonals are perpendicular on each other?
A square.
Will a pentagon always equal 360 degrees?
The external angles will. The internal angles will equal 540o.
Is every rectangle with four sides a square?
only those with 4 equal sides and with internal angles of 90 degrees
How many degrees are the angles of a square?
The 4 equal angles of 90 degrees within a square add up to 360 degrees
What is the degress of a square?
The degrees of a square is 360 degrees. A square has four equal angles, each measuring 90 degrees.
What is the measure of one of the interior angles in a square?
All of the angles in a square are equal, and are 90 degrees.
Squares are made up of what type of angles?
Squares are made up of four ninety degree angles. Another term for these angles are called square angles. These four internal angles make up a square which also has four equal sides. When you add up the degrees of the angles the total is three hundred and sixty degrees.
What shape has the sum of its angles equal 720 degrees?
Assuming you meant 'internal' angles - a hexagon.
Does a parallelogram have all sides the same?
No. A parallelogram has opposite sides parallel.A square is a parallelogram with all sides being equal and all internal angles being 90 degrees.A rectangle is a parallelogram with all internal angles being 90 degrees. and opposite side being equal in length.A rhombus is a parallelogram with all sides equal, but internal angles are not necessarily 90 degrees.
Why is a rectangle a square?
A rectangle is only a square when all the sides are equal and all the internal angles are right angles.
Is a square an equiangular?
True. All of the angles in a square are equal to 90 degrees, so all of the angles are equal to one another.
What is the classification or triangles by side and angles?
An equilateral triangle is one where all sides are of equal length and all internal angles are 60 degrees. An isosceles triangle is one where 2 adjacent angles are of equal size and 2 adjacent sides are of equal length. A scalar triangle is one where no sides are equal in length and no angles are equal in size. A right-angled triangle is one where one of the internal angles is 90 degrees. The internal angles of all triangles always add up to 180 degrees.
What is the different of a square and a diamond?
All four angles of a square are equal (to 90 degrees). In a diamond, which is a rhombus, there are two pairs of equal angles.
