Transformations flashcard 8th grade

Front

What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a figure the same distance in a specified direction.

Front

If point A (2, 3) is translated 4 units up and 2 units left, what is the new point A'?

Back

(0, 7)

Front

What is the result of reflecting a point across the x-axis?

Back

The y-coordinate of the point changes sign, while the x-coordinate remains the same.

Front

If point M (2, -4) is reflected across the x-axis, what is the new point M'?

Back

(2, 4)

Front

What does it mean to reflect a figure across the y-axis?

Back

To reflect a figure across the y-axis, the x-coordinates of all points in the figure change sign.

Front

If point X (-1, 5) is translated 3 units to the left and 9 units down, what is the new point X'?

Back

(-4, -5)

Front

What are the coordinates of a point in Quadrant I?

Back

Both x and y coordinates are positive.

Front

Which axis is the horizontal (left-right) one?

Back

x-axis

Front

What is the definition of the y-axis?

Back

The y-axis is the vertical line in a coordinate plane where x=0.

Front

How do you determine the quadrant of a point (x, y)?

Back

The quadrant is determined by the signs of x and y: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), Quadrant IV (positive, negative).
