This is because for most purposes whole rotations can be ignored. So two and a half turns (which is 900 degrees) is taken to be equivalent to just a half turn (= 180 degrees).
Most figures.
Yes. The sum of the angles in a triangle is 180° All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180° If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle. If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle. If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle. If there is at most one right angle or an obtuse angle, there must be at least two acute angles.
No. A broken clock gives a very precise time, but most of the time it is wrong.
Its not possible to have less than 4 four side that the most idiotic question i ever heard, No Sides, No Angles.
Radio-Telescope measurements are the most precise
A parallelogram always has opposite sides of equal length. Its 4 angles may be right angles, but in most parallelograms they're not. If they are, then that parallelogram is also called a 'rectangle'.
Ofcourse... Most triangles are acute! Remember, acute is less than 90 degrees
A trapezoid can have a maximum of 2 obtuse angles. An obtuse angle is one that measures greater than 90 degrees. In a trapezoid, two of the angles are acute angles (less than 90 degrees) and the other two angles can be either acute or obtuse.
Most of them do not have equal angles.
If you want to measure something and pass the measurements to somebody else, both of you have to agree on the units, and you also have to agree on where 'zero' is. For the system of measurement that is most widely used to describe the location of places on the earth ... latitude and longitude ... the measurements are in angles, and the equator and Prime Meridian are the zeros.
They can vary in size. In its most general form, a trapezoid (or trapezium, outside of North America) is a four-sided figure with exactly one pair of parallel sides. The two parallel sides do not have to be the same length; therefore a trapezoid will have either:Two acute angles (less than 90º) and two obtuse angles (greater than 90º) ORTwo right angles, one acute angle, and one obtuse angle.Case (2) is a special type of Case (1).Regardless of its configuration, the interior angles of a trapezoid always add up to 360 degrees
Most times but not always as for example a trapezoid would be an exception unless it was an isosceles trapezoid
