What is the formula of rotational symmetry?
i rilly dont no is it (n-2)*180?? <--- that's actually for finding the Interior Angles for geometry. the way I remember rotational symmetry is as follows: each shape has to add up to 360 degrees, so you take that and divide it by the number of sides of the shape. Then, you keep adding that answer till you come get to 360. Example: The rotational symmetry for an Octagon: 360/8 = 45 45 + 45 = 90 90 + 45 = 135 135 + 45 = 180 180 + 45 = 225 225 + 45 = 270 270 + 45 = 315 315 + 45 = 360 The degrees for Rotational Symmetry are: 45, 90, 135, 180, 225, 270, 315, and 360. Hope that helps, because it's what helps me.
What turn symmetry does a octagon have?
it has 45 90 135 180 225 270 315 and 360 degree turn semetry
What is a symmetry in math?
When u do pre-algebra u will find a part about degrees like 45 degree and things like that and that is smmetry in math
Does a right angled triangle have symmetry?
It can have, but only if the two smaller angles are 45 degrees, then there is symmetry about the centre-line.
Which type of angle is a complementof an angle with a measureof a 45 degrees?
90 - 45 = 45 So another 45 degree angle is the complement of a 45 degree angle.
What is the angle of rotational symmetry of the figure shown?
45
What rotation symmetry does a regular hexagon have?
A regular hexagon has rotational symmetry of 6. Usually we can figure out the rotational symmetry of most shapes by looking at how many sides they have. Such as an octagon has rotational symmetry of 8 ect. Hope it helped!
Why does an octagon have rotational symmetry?
An octagon has eight-fold rotational symmetry, because rotation of octagon by 45 degrees (one-eighth of a full circle) produces a figure that is superimposible on (or congruent to) the original.

What figure has rotational symmetry of 45 degrees?
an octagon got it off of study island so yeah this anwser is right.
What is the rotational symmetry of an octagon?
Rotational symmetry means it will look the same after being rotated a certain amount. Let's assume that you mean a regular octagon where the sides are all equal in length and the angles are all the same (135 degrees). With such an octagon, if you rotate it one turn to the right (that's 45 degrees), it will look just the same. Rotate another 45° and it is still the same. You can do this 8 times so we say that a regular octagon has an order of rotational symmetry of 8.
How many lines of symmetry does a right triangle have?
Right triangles can have only one line of symmetry. Only right triangles with two 45 degree angles can have a line of symmetry.
Does a right-angled triangle have any symmetery?
If it is a 45-45-90 triangle, it will have symmetry from the 90 degree angle to the midpoint of the hypotenuse.
What turn symmetry does a octagon have?
it has 45 90 135 180 225 270 315 and 360 degree turn semetry
The interior angle of the regular octagon below measures 135, and the octagon has rotational symmetry. Which of the following is the measure of an interior angle after a 90 rotation around the point of symmetry?
A) 68 degrees B) 135 degrees C) 90 degrees D) 45 degrees

How does an isosceles right triangle with vertical axis looks like?
It will look like a right angle triangle with a 90 degree angle and two 45 degree angles and will have one line of symmetry
