![]() Whether it’s the circular moon in the night sky, the triangular roof of a house, or the rectangular layout of a mobile phone screen, geometric shapes are everywhere. In essence, geometric shapes are the building blocks of the world, helping us understand its structure and layout. They are the figures that result from combining specific amounts of points, lines, and angles. Geometric shapes are fundamental aspects of both abstract mathematical concepts and the physical world around us. Whether you are a student, a parent, or an educator, this guide is designed to provide you with a thorough understanding of geometric shapes, brought to you in a manner that is engaging, accessible, and fun – the Brighterly way! What are Geometric Shapes? In this blog post, we will embark on a comprehensive exploration of geometric shapes – their definitions, their types, their properties, and their applications. They form a bridge between the abstract and the tangible, allowing us to visualize mathematical concepts and apply them to our physical environment. Geometric shapes are the fundamental building blocks of the world, and they also serve as essential tools for abstract mathematical thought. The roundness of a ball, the symmetry of a snowflake, the square face of a Rubik’s cube – these are all applications of geometric shapes. Imagine a world where everything we see, touch, and interact with can be defined and understood through geometric shapes. They are the essence of mathematics, brought to life through their tangible representations.Īt Brighterly, we believe in nurturing a child’s curiosity about the world, and geometric shapes offer a perfect starting point for this journey of exploration. They are the foundation upon which our spatial understanding is built, and they form the underlying structure of everything we see and create. So all other quadrilaterals are irregular.In the vibrant universe of mathematics, geometric shapes hold a significant position. The only regular (all sides equal and all angles equal) quadrilateral is a square. and that's it for the special quadrilaterals. one of the diagonals bisects (cuts equally in half) the other.the diagonals, shown as dashed lines above, meet at a right angle.the angles where the two pairs meet are equal.The KiteĮach pair is made of two equal-length sides that join up. (the US and UK definitions are swapped over!)Īn Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles. ![]() NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!Ī trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.Īnd a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides: ![]() Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). The ParallelogramĪ parallelogram has opposite sides parallel and equal in length. ![]() In other words they "bisect" (cut in half) each other at right angles.Ī rhombus is sometimes called a rhomb or a diamond. The RhombusĪ rhombus is a four-sided shape where all sides have equal length (marked "s").Īlso opposite sides are parallel and opposite angles are equal.Īnother interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. The SquareĪ square has equal sides (marked "s") and every angle is a right angle (90°)Ī square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). The little squares in each corner mean "right angle"Ī rectangle is a four-sided shape where every angle is a right angle (90°).Īlso opposite sides are parallel and of equal length. Let us look at each type in turn: The Rectangle Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. There are special types of quadrilateral: They should add to 360° Types of Quadrilaterals Try drawing a quadrilateral, and measure the angles. interior angles that add to 360 degrees:.(Also see this on Interactive Quadrilaterals) Properties ![]()
