As others have stated, the sum of the interior angles of a quadrilateral would be 360 degrees, not 180.
In general, the angles of an n-sided figure would add up to
[180(n - 2)].

The sum of interior angles in a quadrilateral is 360 degrees. 180 is a triangle.
The easy way to work out interior angles is by splitting the shape into the amount of triangles it has - i.e. a square has 2 triangles, therefore 180 x 2 = 360 ...and so on

It should be: The sum of the interior angles of a
convex quadrilateral is 360 degrees.
You can always divide such a quadrilateral
into 2 triangles by drawing a diagonal and the sum of the interior
angles of each triangle is 180 degrees.

No. The sum of the interior angles of a triangle is 180 degrees. Take for instance a rectangle: each interior angle is 90 degrees time 4 sides = 360 degrees, just for this example.

No. 360°
total degrees in a polygon with n sides is
T=180°*(n-2)
for a quadrilateral, n=4 so
T=180°*(4-2)
T=180°*2=360°

Angles in a 4-sided shape ( a quadrilateral )
Add upto 360 degrees
2006-12-27 14:39:09 · answer #6 · answered by SHIBZ 2 · 0⤊ 0⤋
since a quadrilateral is a square and all the angles of a square are 90 degrees 90 * 4 = 360

No, 360 degrees. A triangle is 180 degrees.

no, it's 360. think about it, you can split the quadrilater into two triangles. and the interior angles in every triangle add up to 180°.

False. They sum to 360°.
