Answer: 90 degrees clockwise
This is equivalent to 270 degrees counterclockwise
The rule for either rotation is
The x and y coordinates swap places, and the new second coordinate flips from positive to negative (or vice versa).
The diagram below shows an example of this for the point (-4,-2) rotating to (-2, 4). The center of the rotation is the origin (0,0).
Answer:
The sum of the interior angle is 108°
Step-by-step explanation:
To find the sum of the interior angle, you need this equation:
(The variable
represents the number of sides does a shape have).
-Count the sides of the shape:
The following polygon shown, has 5 sides.
-After you have the number of sides of the polygon, use the number of sides for the equation and it will be written as:
-Then, you solve:
So, the sum of the interior angle is .
