What is 12.5 percent of a circle written in degrees?
45 degrees A circle has 360 degrees. 12.5% * 360 degrees = 0.125 * 360 degrees = 45 degrees
What type of angle sum up to 90?
45 degrees and 45 degrees.
Half of a right angle is how many degrees?
a right-angle is 90 degrees so half that 45 degrees your answer is 45 degrees
What has more thermal energy a bath tub at 45 degrees or a cup of coffee at 90 degrees?
Bathtub at 45 degrees
What is a measure of each angle formed by bisecting a right angle?
45 degrees. 45 degrees
What is the angle of rotational symmetry of the figure shown?
45
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 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!
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.
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
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.
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.
A right triangle can be an isosceles triangle?
Yes, because if you halve a square across a diagonal line of symmetry then one corner has 90 degrees and the other two are 45 degrees.
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
What would be the sum of the interior angles of a 45 sided figure?
They would add up to 7740 degrees
Supplement of 45?
135 degrees is the supplement of 45 degrees. When you minus 45 degrees from 180 degrees you will get 135 degrees which is the supplement angle of 45 degrees.
How many lines for symmetry does a right angle triangle have?
None, unless it's also isosceles (1.e. 45 degrees for the other two sides).
