Some textbooks might write the dimensions of a rectangle as base and height instead of length and width. Where l is the length and w is the width of the rectangle. The area of a rectangle is the product of its length and width. This is the proportion of a line segment whose area is equal to that of a golden rectangle. The golden ratio (or phi) is the proportion 1.6180339. One of the most well-known lines of symmetry is the golden ratio. Symmetry in a rectangleĪ rectangle has 2 lines of symmetry and a rotational symmetry of order 2, which means that it can be rotated in such a way that it will look the same as the original shape 2 times in 360°. Therefore, there are three different lines of symmetry. A rectangle is a square when all of its sides are congruent. SquareĪ square has four congruent sides and four right angles, so it is also a rectangle. A rectangle has two lines of symmetry along the line segment joining the midpoints of the opposite sides. Therefore, △ABD≅△CDB by the Side-Angle-Side postulate. A rectangle is formed of 2 lines of symmetry which divides it into two identical parts. ∠A≅∠C since the interior angles of a rectangle are right angles. AB≅ CD and AD≅ BC since opposite sides of a rectangle are congruent. Rectangles also have four right angles and two pairs of lines, with the lines in each pair having equal lengths. One line of symmetry divides a rectangle in half horizontally, and the other line divides the shape in half vertically. Each diagonal divides the rectangle into two congruent right triangles.ĭiagonal BD divides rectangle ABCD into triangles ABD and CDB. How many lines of symmetry does a rectangle have Rectangles are geometric shapes with two lines of symmetry. The two diagonals ( AC and BD in the rectangle below) are congruent and bisect each other. Angles A, B, C and D equal 90° in the rectangle shown below. Angles of a rectangleĪ rectangle contains four interior right angles. The longer sides of a rectangle are typically referred to as its length while the shorter sides are referred to as its width. The opposite sides of a rectangle are congruent and parallel to each other. Introduction, continued Squares Because squares have four equal sides and four equal angles, squares have four lines of symmetry. Many objects around us are rectangular in shape, such as a book, a phone, a door, a card, and many more. Rectangles are one of the most common shapes you will see in daily life. In case of any queries, you can reach back to us in the comments section, and we will try to solve them.Home / geometry / shape / rectangle RectangleĪ rectangle is a quadrilateral with four right angles. We hope you find this article on Symmetry helpful. Download more important topics, notes, lectures and mock test series for Class 6 Exam by signing up for free. Can you explain this answer in English & in Hindi are available as part of our courses for Class 6. Reflexive symmetry is also known as mirror symmetry.Īns: The line which divides or cuts the shape or object into two equal parts is called an axis of symmetry or line of symmetry. Solutions for How many lines of symmetry does a rectangle havea)Oneb)Twoc)Threed)Man圜orrect answer is option B. How many lines of symmetry does a circle have?Īns: The number of lines of symmetry in a circle is infinite.Īns: When an object is rotated in any particular direction, and the image formed is identical to the original, it is known as rotational symmetry.Īns: Reflexive symmetry is the type of symmetry in which one half of the object or shape reflects another half of the object or shape. How many lines of symmetry does a parallelogram have?Īns:A parallelogram has no line of symmetry. How many lines of symmetry does a rectangle have?Īns:A rectangle has two lines of symmetry. FAQs on SymmetryĪns: Symmetry is the process of comparing two identical shapes. 45 degree line, which may justly be called the line of symmetry, and which. We have also discussed transitional, reflection, rotational, and glid symmetry. 46 2 The intermediate stream line are hyperbolas whose shortest radii. We have discussed the various lines of symmetry, such as horizontal, vertical, and diagonal lines of symmetry, and studied the figures with one line of symmetry, two, three, four, and infinite lines of symmetry with the help of examples. And now that answer is only helpful if we know what a line of symmetry is. We studied the symmetrical or asymmetrical figures with the help of examples. A shape is symmetrical if it has at least one line of symmetry, a line of symmetry. This article discussed the definition of symmetry-the line of symmetry that divides or cuts the figure or object into two mirror images. Therefore, the circle has infinite lines of symmetry.
