A parallelogram is transformed according to the rule (x, y) → (x, y). Which is another way to state the transformation?
Ro, 90°
Ro, 180°
Ro, 270°
Ro, 360°

The parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).

For 360 degrees rotation, the coordinates before and after the transformation will be the same.

According to this rule, the transformation of (x,y) gives (x, y)

Thus, the parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).

Ro, 360°

Step-by-step explanation:

Given

(x,y) transformed to (x,y)

Required

Determine the transformation

We have the following observations

Before transformation, the coordinates are: (x,y)

After transformation, the coordinates are: (x,y)

In other words, the coordinates before and after the transformation are the same.

This implies that there is a 360 degrees rotation.

Simply put, when there are no changes in the pre and post transformation of a point, line or shape, then the transformation is 360 degrees

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
