Which statement accurately explains whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure ACB onto itself? a coordinate plane with figure ACB with point A at 1, 1, C at 3, 4 and B at 5, 1

Yes, A″C″B″ is located at A″(1, 1), C″(4, 3), and B″(1, 5)
Yes, A″C″B′ is located at A″(1, 1), C″(3, 4), and B″(5, 1)
No, A″C″B″ is located at A″(1, 1), C″(4, 3), and B″(1, 5)
No, A″C″B″ is located at A″(1, 1), C″(3, 4), and B″(5, 1)

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.

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
