Jenny has a problem where she has to measure an angle that is drawn on the paper. She is going to use this protractor to do so. How precise can she be?
to the nearest ten degrees i think
(A) nearest one degree.
To determine the precision of the protractor, we need to look at its scale or subdivisions. Typically, a protractor is divided into degrees, with each degree further divided into smaller increments.
The most common protractors have markings at every 1 degree, allowing for measurements with a precision of 1 degree. This means that Jenny can measure angles accurately to the nearest degree.
However, some protractors have additional markings or subdivisions that provide greater precision. For example, a protractor with markings at every half-degree (0.5 degrees) would allow Jenny to measure angles with a precision of 0.5 degrees.
If Jenny requires even more precise measurements, she can use a protractor with markings at every quarter-degree (0.25 degrees) or even smaller subdivisions. These protractors would allow her to measure angles with a higher level of accuracy and precision.
In summary, the precision of a protractor depends on its scale or subdivisions, ranging from 1 degree to smaller fractions such as 0.5 degrees, 0.25 degrees, or even more precise measurements.
