Triangles polygons and angle properties
WebPolygons are 2-D figures with more than 3 sides. Interior angle = 180º (n-2)/n, where n refers to the number of sides. The sum of interior and exterior angles at a point is always 180º as they form a linear pair of angles. For an 'n'-sided polygon, the number of diagonals can be calculated with this formula, n (n-3)/2. WebA triangle is a three-sided polygon that has 3 angles, and 3 vertices. Learn the definition of triangles, their types, parts, properties using a variety of examples. A triangle is a three …
