Step-by-step explanation:
To complete the square
add ( half the coefficient of the x- term )² to x² - 2x
x² + 2(- 1)x + 1
(x² - 2x + 1 = (x - 1)²
Answer:
No. 1: y = 90 (vertically opposite angles)
Also, x = 9. To find x, we'll have:
No. 4: y = 62 (vertically opposite angles)
Also, x = 12. To find x, we have:
Answer:
A. Quadrilateral 1 and quadrilateral 2 are congruent because quadrilateral 2 can be created by rotating and then translating quadrilateral 1.
Step-by-step explanation:
Both have the same dimensions, so there has been <em>no dilation</em>. The only answer choice describing a rigid transformation is choice A.
To obtain ΔA''B''C'', ΔABC is reflected across the x-axis and dilated with a scale factor of 2
<h3>What is a transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
Rigid transformation are transformation that preserve the shape and size of the figure.<em> Rotation, reflection and translation</em> are rigid transformations.
To obtain ΔA''B''C'', ΔABC is reflected across the x-axis and dilated with a scale factor of 2
