What do you call a polygon with 3 sides? A three-sided polygon is a triangle. Which best describes a regular polygon? In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular poly...
The interior angles of a polygon are, as the name suggests, the angles formed on the inside where the polygon's edges meet. Before we start looking at the interior angles of many-sided polygons, we will start with three-sided polygons, otherwise known as triangles. We can quickly work o...
This page includes a lesson covering 'the interior angles of a polygon' as well as a 15-question worksheet, which is printable, editable and sendable. The interior angles of a polygon are the angles between two sides of a polygon. The sum of the interio
As a consequence of these properties, a 3-sided polygon (triangle) does not have diagonals, since all its vertices are adjacent to each other. Figure 2: A triangle does not have diagonals. In the case of 4-sided polygons, a diagonal can be cut into two congruent triangles, as shown ...
1.(Mathematics)geometrya three-sided polygon that can be classified by angle, as in an acute triangle, or by side, as in an equilateral triangle. Sum of interior angles: 180°; area: base × height 2.any object shaped like a triangle ...
A triangle is a three-sided polygon. We will look at several types of triangles in this lesson.To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For ...
h. hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it . it is applicable to all types of triangles , whether it is scalene, isosceles or equilateral. to be noted, the base and height of the triangle are perpendicular to each ...

18. Three exterior angles of a 8-sided polygon are 30", 71", 74". The size of each remaining exterior angle of the polygon is y(a) Calculate the value of y.[2](b) Hence, find(i) the smallest interior angle of the polygon.[2](ii) the largest interior angle of the polygon.[2...
With the help of educational experts, we explain how polygons are taught in primary school, with examples of regular and irregular versions of each multi-sided shape. What is a polygon? A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the ...
