How do you know that the sum of an angle in a circle is 360?
It's actually 2(pi), you technically need to say 360 degrees. I believe we defined it to be that, but you can prove that it's 360 degrees: Draw a diameter. Draw a second diameter perpendicular to the first. You now have four right angles. Right angles measure 90 degrees. 90 * 4 = 360 Hence, there are 360 degrees in the circle.
What are the angles in a circle?
There are 360 degrees around a circle
What is the sum of the angles of a circle?
360 degrees
How angles formed?
Angles are formed by measuring a line from the centre of a circle to the edge of the circle marked in degrees, minutes and seconds. A protractor and ruler are commonly used to measure and draw angles.A complete circle is 360 degrees.A half circle is 180 degrees.A quarter circle is 90 degrees.A right-angle triangle has one corner with an angle of 90 degrees. The two other angles are both 45 degrees. 90 + 45 + 45 = 180 degrees (half a circle).The right-angle triangle is actually half of a square. If two such triangles were to be joined together to form a square, all angles will add up to 360 degrees.90 + 45 + 45 =180 x 2 = 360 degrees.

What is the symbol for temperature when being measured in degrees celsius?
The symbol is °C, in which the little circle is 'degrees' just like when measuring angles in degrees. The C is for Celsius.
Why is measuring the diameter of a circle easier than measuring the its circumference?
Because the diameter is a straight line.
How many degrees are in a circle with a diameter of 10 units?
A circle has 360 degrees, whatever its diameter.
How do you know that the sum of an angle in a circle is 360?

Can a diameter of a circle divide an angle in the circle into congruent angles?
Yes.
How do you get the diameter?
The diameter of a shape is formulated by measuring from one edge of a circle to the other.
What are the angles in a circle?
There are 360 degrees around a circle
What is the diameter of a skating circle?
The diameter of a skating circle will vary depending on the size of the skating rink. The diameter is determined by measuring from the middle of the circle from one side to the other.
If the radius of a circle is 6 yd the diameter is?

What is the difference degrees and meridians?
Meridians are lines on a sphere (or other geometric solid) all of which go through the poles. Degrees are a unit of measurement of angles and temperature and concentration, and some other things. As a unit for measuring angles, meridians are measured in degrees. There are 360 degrees in a complete circle.
How many dregrees are in a circle?
There are no angles in a circle but the circle covers 360° (degrees)
