How can you prove that the sum of the four interior angles in all quadrilaterals equal 360 degrees?
If you accept that the sum of the angles in a triangle is 180 degrees, then picture this. A quadrilateral shape is two triangles. If you draw a line between one pair of opposite corners in quadrilateral shape, you have two triangles that share a common side. The sum of the angles in the quadrilateral must equal the sum of the angles in the two triangles. 2 x 180 = 360
Why do you subtract 2 from n to find the sum of interior angles?
This has to do with the way in which the sum of the angles is derived. First you select a point inside the polygon and then join that point to each of the vertices. For a polygon with n sides, this gives rise to n triangles. The sum of the 3 angles of any triangle is 180 degrees. So the sum of the angles of all the triangles is n*180 degrees. Now, the "outer" angles of these triangles correspond to the interior angles of the polygon. But the sum also includes the angles formed arounf the central point. The sum of all the angles around this central point is 360 degrees. This is not part of the sum of the interior angles of the polygon and so must be subtracted. Thus, the interior angles of a polygon sum to n*180 - 360 degrees or 180*(n- 2) degrees.
What is the sum of the interior angles of any triangles?
180
What are the names of the four triagles?
What are 'triagles'? If you mean 'triangles' ; note the spelling. The four types of triangle are;- Equilateral ; All sides the same length , all angles at 60 degrees. Isosceles ; Two lines the same length and two anglesthe same value Right-angled ; One of the three angles MUST be a right angle (90 o). Scalene ; No sides the same length , and no angles the same value. NB In all four types of 2-dimensional triangles, the sum of the angles is ALWAYS 180 o . NNB For triangles drawn on a 3-dimensional surface (a sphere), the sum of the angles can be greater than 180 o. NNNB Tringles can also be known as 'trigons' (polygons), from which we have the word 'trigonometry' (Measuring Triangles).
