How many Reflectional symmetry does an equilateral triangle have?
The division of triangles into scalene, isosceles, and equilateral can be thought of in terms of lines of symmetry. A scalene triangle is a triangle with no lines of symmetry while an isosceles triangle has at least one line of symmetry and an equilateral triangle has three lines of symmetry.
Does an equilateral triangle have Reflectional symmetry?
Equilateral triangle has six symmetries (rotations and reflections), described by the dihedral group D 3.
How many number of lines of symmetry are there in an equilateral triangle?
3 lines of symmetry Equilateral triangle have all three sides equal and all three angles equal showing 3 lines of symmetry.
Which triangle has Reflectional symmetries?
An isosceles triangle is a type of triangle that has exactly one-fold reflection symmetry at all times.

How does an equilateral triangle have three lines of symmetry?
The first line is drawn from vertex A passing through the side BC, the second line is drawn from vertex B passing through the side A, the third line is drawn from vertex C passing through the side AB. Therefore, an equilateral triangle has 3 lines of symmetry.
Which figure is reflectional symmetry?
Symmetric geometrical shapes Triangles with reflection symmetry are isosceles. Quadrilaterals with reflection symmetry are kites, (concave) deltoids, rhombi, and isosceles trapezoids. All even-sided polygons have two simple reflective forms, one with lines of reflections through vertices, and one through edges.
What is reflectional symmetry in math?
Reflection symmetry is also known as line symmetry or mirror symmetry. It states that if there exists at least one line that divides a figure into two halves such that one half is the mirror image of the other half.
What is meant by reflectional symmetry?
Reflection symmetry is also known as line symmetry or mirror symmetry. It states that if there exists at least one line that divides a figure into two halves such that one half is the mirror image of the other half.
What is reflectional symmetry and examples?
Reflective symmetry is a type of symmetry where one-half of the object reflects the other half of the object. It is also known as mirror symmetry. For example, in general, human faces are identical on the left and right sides. The wings of most butterflies are identical on both sides, the left and right sides.
Why does an equilateral triangle have 3 lines of symmetry?
Symmetry is observed when two or more parts are identical after a flip, slide, or turn. An equilateral triangle is one that has all sides equal to each other and every angle is equal to 60 degrees.
Which triangle has no line of symmetry?
A scalene triangle is a triangle that has three unequal sides and hence it has no line of symmetry.
How do you draw a line of symmetry for an equilateral triangle?
The first line is drawn from vertex A passing through the side BC, the second line is drawn from vertex B passing through the side A, the third line is drawn from vertex C passing through the side AB. Therefore, an equilateral triangle has 3 lines of symmetry.
What do you mean by reflectional symmetry?
Reflection symmetry is a type of symmetry which is with respect to reflections. Reflection symmetry is also known as line symmetry or mirror symmetry. It states that if there exists at least one line that divides a figure into two halves such that one half is the mirror image of the other half.

What type of symmetry does an equilateral triangle have?
Answer: An equilateral triangle has 3 lines of symmetry.
How many symmetry does a triangle have?
three lines of For every triangle that's equilateral, for every triangle where every side is the same length, it will have three lines of symmetry.
How many Reflectional symmetry does the regular hexagon have?
Let's consider a regular Hexagon as an example. A regular hexagon has all its sides Congruent and each of the Angle measure. A regular hexagon has a number of lines of reflection: three along the lines joining the midpoints of its opposite sides and three along the Diagonal. Thus, a hexagon has reflection symmetry.
How many reflectional symmetry are there?
There are four lines of reflection that carry the square onto itself. These lines of reflection will always be the lines of symmetry. Two lines of symmetry separate the square into two equal rectangles, whereas the other two separate the square into two equal triangles.
How many reflectional symmetry does a rectangle have?
A rectangle is an example of a shape with reflection symmetry. A line of reflection through the midpoints of opposite sides will always be a line of symmetry. A rectangle has two lines of symmetry.
