In geometry, a triangle is a two-dimensional object (a polygon) with three straight sides. There are different types of triangles, and we can classify a triangle as a certain type based on how the sides of the triangle relate to one another. ...
A polygon is a flat, closed shape with straight sides. Each polygon also has the same number of sides as it has angles. For example, a triangle, which is a polygon, has three sides and also has three angles. Trapeziums:Trapeziums, also called trapezoids, are closed, planar shapes ...
Right Triangle: A right triangle is a triangle that has a right angle. The Pythagorean Theorem is a relationship among the sides of a right triangle. Square: A square is a polygon with four sides of equal length and at right angles to each other. Trapezoid: A trapezoid is a quadrilateral...
A scalene triangle is a triangle whose all sides are unequal and all angles have different measures. We know that a triangle is a three-sided polygon that consists of three edges and three vertices. There are three types of triangle based on the length of its sides:...
Angles of a Regular Polygon: In mathematics, a regular polygon is a polygon with sides of equal length and angles of equal measure. When a polygon is regular and it hasnsides, we can determine the measure of one of its angles using the formula(n−2)×180on. ...

Every triangle and regular polygon has a unique incircle, but in general polygons with 4 or more sides (such as non- square rectangles) do not have an incircle. A quadrilateral that does have an incircle is called a Tangential Quadrilateral. ...

Polygons in Geometry:It comes as no surprise that there are many different types of shapes within the study of geometry. One type of shape that is studied extensively in geometry is the polygon. A polygon is a two-dimensional shape that has straight sides, and we often classify polygons ...
