Because if you walked around a square you would have to turn four times at 90 degrees which amount to 360 degrees.
Likewise, if you walked around an equilateral triangle you would have to turn three times at 120 degrees which makes 360 degrees.
That is why that for any polygon the total sum of exterior angles are always 360 degrees.

Answer #1.5:
EVERY angle outside the vertex of EVERY regular polygon, between two of
its sides, is a reflex angle. But that's not the definition of an exterior angle.
An exterior angle is the angle between one side and an EXTENDED adjacent
side. That angle is 90 degrees in a regular quadrilateral, and less than 90 degrees
in a polygon with more than 4 sides. Regardless of how many sides the polygon
has, the exterior angles always add up to 360 degrees, as explained above in
Answer #1.
A rhombus is a quadrilateral with all sides of equal length. A reflex angle is an angle greater than 180 degrees. A rhombus does not have a reflex angle because the sum of its interior angles is always 360 degrees, which means all its angles are less than 180 degrees.
A square always has a sum of 360 degrees for the interior angles.
Any - it can be acute, right, obtuse, reflex - take your pick! A regular octagon, on the other hand, will have all internal angles measuring 135 degrees. That is, they will all be obtuse.
NO!!! It can be a Rhombus. Square ' 4 equal sides and four angles at 90 degrees. Rhombus' 4 equal sides, but no angles at 90 degrees.
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.
Yes!!!! They are the four 'outside' angles of the square. Each angle is 270 degrees , which are REFLEX.
360 degrees
4 INSIDE right angles. and 4 (outside) REFLEX right angles.
Each of the four interior angles of a square is 90 degrees in size, making the exterior angles 270° each (360° - 90°).
Their exterior angles add up to 360 degrees
pentagon because it has an obtuse angle and a square has right angles- Actually, a regular pentagon has larger interiorangles, however, for exterior angles, a square beats a regular pentagon, because all exterior angles of a shape equals 360 degrees. A square has 4 angles, and 360/4= 90. A regular pentagon has 5 angles, and 360/5=72. If the pentagon isn't regular, then one exterior angle can be larger than 90 degrees.
They are both quadrilaterals and they both have interior and exterior angles of 360 degrees.
Each angle of a square is 90 degrees. Subtract that from 360 to get...270 degrees for each of the four exterior angles. Multiply that by 4 to get a total of....1080. I think that's how it works..someone correct me if I'm wrong.
They are both 2D shapes and have exterior angles that add up to 360 degrees
A rhombus is a quadrilateral with all sides of equal length. A reflex angle is an angle greater than 180 degrees. A rhombus does not have a reflex angle because the sum of its interior angles is always 360 degrees, which means all its angles are less than 180 degrees.
360 degrees and it's probably a square
They are all polygons whose exterior angles add up to 360 degrees.
