Why is counterclockwise rotation is positive and clockwise is negative?
Counterclockwise rotation is considered positive based on the standard convention used in mathematics, particularly in trigonometry and coordinate geometry. This convention aligns with the orientation of the Cartesian coordinate system, where angles are measured from the positive x-axis. Clockwise rotation, on the other hand, is deemed negative as it moves in the opposite direction. This differentiation helps maintain consistency in mathematical equations and calculations involving angles.
What is a ccw origin in math?
In mathematics, particularly in geometry and coordinate systems, a "CCW origin" refers to a counterclockwise (CCW) orientation of angles or rotations around a point, typically the origin of a coordinate system. In this context, positive angles are measured in a counterclockwise direction from the positive x-axis. This convention is commonly used in trigonometry and computer graphics to define the orientation of shapes and the rotation of objects.
How does reflecting or rotating a figure change the interior angles of the figure?
The angles have the same measure. In the reflection the order of the angles are changed from clockwise to counterclockwise.
Standard methods of measuring angles?
1/3 rotation counterclockwise
What are the first signs that the landlady is very odd?
angles and saxons
Positive rotation of a vector is?
counterclockwise

Do positive rotations go clockwise or counter clockwise?
Positive rotations typically go counterclockwise.
What does a and a and equall?
a(-)and a(-)=positive a(+)and a(+)=positive but a(-)and a(+) or a(+)and a(-)= negative so two signs the same is positive and two signs that are different are negative.
What are the first signs that the landlady is very odd?
angles and saxons
Why are quadrants numbered counterclockwise?
It is because angles are measured counter-clockwise for the horizontal x-axis.
Why are cosines positive and negative?
Because the cosine of some angles is positive and the cosine of some other angles is negative.
What is the direction of angular motion associated with a positive () sign?
The direction of angular motion associated with a positive () sign is counterclockwise.
Why do you get a positive answer when you multiply two alike signs?
You get a positive answer when multiplying two alike signs because since its an even number of positive signs, the number will be positive. For example, -2 x -4= 8 since there are an even amount of negative signs.
When dividing a positive number by a positive number the quotient is?
The answer is always positive. If the signs are the same (positive by positive, negative by negative), then the quotient is always positive. If the signs are different (positive by negative, negative by positive), then the quotient is always negative.
Why go counterclockwise in geometry?
Acute angles are usually measured this way. It is nothing more than a convention.
