Answer: A. Figure ABCD is similar to figure A'B'C'D'.
Step-by-step explanation:
Given : Figure ABCD is reflected about the x-axis to obtain figure A'B'C'D'.
Since a reflection is a rigid transformation which produces congruent images.
⇒ Figure ABCD must be congruent to figure A'B'C'D'.
⇒ Figure ABCD has same size as figure A'B'C'D'.
⇒ Figure ABCD must be similar to figure A'B'C'D'. [ ∵ If two figures are congruent then they are also similar.]
Reflection preserves side length and measure of angles .
⇒ Corresponding angles and side lengths of figure ABCD must be congruent to figure A'B'C'D'.
⇒ The measure of angle D is equal to the measure of angle D'.
Hence, the statement best describes the relationship between the two figures is :-
A. Figure ABCD is similar to figure A'B'C'D'.
Answer:
Step-by-step explanation:
Intersecting lines make equal opposite angles
2x + y = 50 - y
2x = 50 - 2y
x = 25 - y
A straight line represents 180°
4x + 6y + 2x + y + 2x + 3y = 180
8x + 10y = 180
8(25 - y) + 10y = 180
200 - 8y + 10y = 180
2y = -20
y = -10
x = 25 - (-10)
x = 35
Refer to the image for the graph of the lines.
The common form of the equation of a line is y = mx + c, where m is the slope of the line and c is a constant.
We need to draw any line with a slope m = 2, and
another line with a slope m = -2.
Disclaimer: Let us assume that the constant c = 0.
Then the equation to the line with a slope of "positive" 2 is given by
y = 2x
Then the equation to the line with a slope of "negative" 2 is given by
y = -2x
Refer to the attached image for the graph of the lines with the slope of "positive" 2 and "negative" 2.
f: green line indicates a line with a slope of "positive" 2.
g: blue line indicates a line with a slope of "negative" 2.
