Answer:
Order of rotational symmetry is 6.
Step-by-step explanation:
The number of positions the object looks the same in a 360-degree rotation is known as order of symmetry.
In the given figure, we have 3 line bisecting each other at a point which is the center of the rotation.
Now, we have 6 segments, each segment have a triangle in clockwise direction. All triangles are congruent.
It means central angle divided in 6 equal parts.
It means after each 60 degrees we get the same figure.
Since, 6 times the positions of figure looks the same in a 360-degree rotation, therefore, the number of rotational symmetry for the figure is 6.
Rate of change of line that passes through the given points is 1
Step-by-step explanation:
The ratio of vertical and horiontal changes is called the rate of change of a line. It is called slope which is denoted by m.
The formula for slope when (x1,y1) and (x2,y2) are the points on line is given by:
Given
(x1,y1) = (-6,-6)
(x2,y2) = (-2,-2)
Putting the values in the formula
Rate of change of line that passes through the given points is 1
