A rotation is an isometric transformation that turns every point of a figure through a specified angle and direction about a fixed point.
To describe a rotation, you need three things:
Direction (clockwise CW or counterclockwise CCW)
Angle in degrees
Center point of rotation (turn about what point?)
The most common rotations are 180° or 90° turns, and occasionally, 270° turns, about the origin, and affect each point of a figure as follows:
Mark me as brainliest! :D Hope it helps
Answer:
625
Step-by-step explanation:
basically, half of 500 is 250 halve that you get a quater of 500 (25%)
500+125=625

Answer:
Step-by-step explanation:
The slope is the difference in y-coordinates of the 2 points divided by the corresponding difference in x-coordinates.
For example:
Find the slope of the line joining the points (3, 5) and (-2, 1)
The slope = (5 - 1) / (3 - (-2))
= 4/(3+2)
= 4/5.
NOTE:
You would get the same result if you reversed the values
- that is (1 - 5)/(-2 - 3
= -4/-5
= 4/5.
The important thing to remember is to use <em>corresponding </em>values in the calculation.
