s = rθ
s=arc length
r=radius length
θ= degree measure in radians
this formula shows that arc length depends on both degree measure and the length of the radius
therefore, it is possible to for two arcs to have the same degree measure, but different radius lengths
the circumference of a circle is a good example of an arc length of the whole circle

If lines are not parallel can you still determine the angle measure?
yes you can still determine the angle measure!
What is the perimeter of 5000 acres in meters?
You can't tell the linear dimensions from knowing only the area. There are an infinite number of shapes that all have the same area. Even if you consider only rectangles, there are still an infinite number of different rectangles, all with different lengths and widths, that all have areas of 5,000 acres.
What is a 45 degree angle?
a 45 degree angle is less than a 90 degree angle and more than a 30 degree angle Its like cutting a round Pizza into 8 equal slices, one of the slices is a 45 degree angle, two slices would be a 90 degree angle. 360 degrees is the circle of the whole pizza. It doesn't matter the size of the circle, or Pizza if its easier, the angles will still be the same.
Does a trapezoid have rotational symmetry?
A trapezoid does not have rotational symmetry. Rotational symmetry occurs when a shape can be rotated by a certain angle and still appear the same. In a trapezoid, the angles and side lengths are not equal, so rotating it will result in a different shape. Therefore, a trapezoid does not have rotational symmetry.
How do you measure a room for 13 X20 tile?
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
A quadrilateral in which all sides have different lengths this describes?
There is no special name. And some quadrilaterals with special characteristics (eg a trapezium) could still have all sides of different lengths.
How much time will a 33 degree angle measure when observed under a microscope that magifies 10 times?
It will still measure 33 degress.
Is it true or false that the lengths of the sides of a triangle affects the size of the angles of the triangle?
no it doesn't matter what size an equalateral triangle is, it still has 60 degree angles
What shape has 4 straight lines different lengths?
Any 4 sided shape is a quadrilateral. If all sides are of different lengths, that is as specific as you can get. Other 4 sided shapes have special characteristics about them, so they are given special names. They are still quadrailaterals.
How do we still use the number system based on 60?
In minutes and seconds - as subdivisions of an hour or degree (angular measure).
Can two triangles be similar but not congruent?
Yes. The triangles have the same angle measures but different, similar side lengths. Think of two different sized equilateral triangles. One can have side lengths of 6 inches while the other has side lengths of 20 inches, but they still have congruent angles of 60 degrees. Each ratio of side lengths is equal [6/20=6/20=6/20].
What are the units in the metric system that are use to measure length?
All lengths are measured in metres. Kilometres just means thousands of metres, millimetre means thousandths of metres, they are both still counting in metres.
How is the first calendar different from the modern calendar?
The older calender was based on the stars, and sun. Days were still 24 hours but they made their own month and year lengths.
How is the first calendar different from the modern-day calendar?
The older calender was based on the stars, and sun. Days were still 24 hours but they made their own month and year lengths.
What does it mean to minor in a degree and how does it differ from majoring in a degree?
Minoring in a degree means focusing on a secondary area of study alongside your main major. It requires fewer courses and credits compared to a major, allowing you to explore a different subject while still earning your primary degree.
If lines are not parallel can you still determine the angle measure?
yes you can still determine the angle measure!
An acute angle could measure exactly 90 degrees?
No, an acute angle must measure between 0 and 90 degrees exclusive. So if it were 89.999999999 degrees, it is still an acute angle, but once the degree hits 90, it can only be a right angle.
