How Many Lines of Reflection Symmetry does a Rectangle Have?Ī rectangle is a regular polygon having two lines of symmetry and four sides. Also, a straight line has infinite lines of symmetry.
Although lines can be horizontal, vertical, or slanting. In most cases, the lines of symmetry are straight only. Do Lines of Symmetry have to be Straight? Yes, a square has a reflection symmetry having four lines of reflection, two on midpoints on the sides and two through the opposite vertices (diagonals). What does Reflection Symmetry Look Like?įor any shape, reflection symmetry looks when a central dividing line (a mirror line) can be drawn on it, proving that both sides of the shape are exactly the same or reflections of one another. When a shape or pattern is reflected in a line of symmetry or forms a mirror image, then it is considered to show reflection symmetry. How many lines of symmetry does an isosceles triangle haveįAQs on Reflection Symmetry What is Meant by Reflection Symmetry?.A figure can have one or more lines of reflection symmetry depending on its shape and structure.Ĭheck out these interesting articles to know about reflection symmetry and its related topics.Reflection symmetry can also be observed in inkblot paper.An object and its image are symmetrical with respect to its mirror line.
All regular polygons are symmetrical in shape.The reflection of trees in clear water, the reflection of mountains in a lake are amongst the commonly seen examples of reflection symmetry around us.A generic trapezoid will certainly not have reflection symmetry but an isosceles trapezoid will have reflection symmetry as the line connecting the midpoints of the bases make up a line of symmetry.A rectangle has two lines of symmetry, that is lines through the midpoints of opposites sides.A square has 4 lines of symmetry, which are lines through the midpoints of opposites sides, and lines through opposite vertices make up the four lines of symmetry.Some of the common examples of reflection symmetry are given below:
