How many lines of symmetry does a decagon have?
10 lines of symmetry
Hence, a regular decagon has 10 lines of symmetry.
How much lines of symmetry are in a square?
A square is a regular polygon . It has four lines of symmetry and four sides.
Does a decagon have infinite lines of symmetry?
A regular decagon has 5 lines of symmetry that go through opposite vertices and 5 lines of symmetry that go through the midpoints of opposite sides. There is also a line of symmetry perpendicular to the plane that passes through the centre of the decagon.
How many lines of symmetry does a Dodecagon have?
12
Dodecagon/Line of symmetry
A regular dodecagon is a figure with sides of the same length and internal angles of the same size. It has twelve lines of reflective symmetry and rotational symmetry of order 12.
Does a decagon have 10 lines of symmetry?
Answer: A regular decagon has 10 lines of symmetry.
Does a decagon have translation symmetry?
The angle of rotation can be 36° or any multiple thereof (notice, 360 divided by 10 is 36). C) There is no translation that moves a regular decagon onto itself, so it does not have translation symmetry.
Does a square have 6 lines of symmetry?
A shape can have more than one line of symmetry. Thus a rectangle has two lines of symmetry, an equilateral triangle has three lines of symmetry, and a square has four. A circle has an infinite number of lines of symmetry since it can be folded about any diameter.
What is the rotational symmetry of a decagon?
Order 10
Decagon/Rotational symmetry
What are the angle of rotation for a decagon?
So a regular decagon has rotational symmetry with a 36 degree angle of rotation. Keep in mind the decagon must be regular which mean the sides are all congruent and the angles are all equals.
How many lines of symmetry are there in a square of sides 3.8 cm?
The number of lines of symmetry in a regular polygon is equal to the number of sides. There are 4 lines of symmetry in a regular square.
How many lines of symmetry does a regular decagon have?
A regular decagon has 5 lines of symmetry that go through opposite vertices and 5 lines of symmetry that go through the midpoints of opposite sides.
How do you determine lines of symmetry?
Each parabola has a line of symmetry. Also known as the axis of symmetry, this line divides the parabola into mirror images. The line of symmetry is always a vertical line of the form x = n, where n is a real number. This tutorial focuses on how to identify the line of symmetry.
What shapes have lines of symmetry?
Other examples of shapes that have at least one line of symmetry include a square, with four lines of symmetry, and an equilateral triangle, with three lines of symmetry. When one half of an object is the reflection of the other half, the object is said to have line or reflection symmetry.
Does a decagon have rotational symmetry?
All of them, except the pentagon, have bilateral (reflection) symmetry through two perpendicular lines. Some have additional symmetries. Specifically, the decagon has tenfold rotational symmetry (rotation by 36°); and the pentagon has fivefold rotational symmetry (rotation by 72°).
