Which diagram can be used to prove △ABC ~ △DEC using similarity transformations? Triangle A B C is rotated about point C and then is dilated to form smaller triangle C E D. Triangle A B C is reflected across side A C and then is dilated to form smaller triangle C E D. Triangles A B C and C E D have different angle measures. Right triangle A B C is shown. Line segment D E is drawn near point C to form triangle D E C.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

here is a big fat

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
