Honors Geometry Q1 Progress Check Review

Front

Describe the rotation that occurs in coordinate notation: (x, y) --> ?

Back

(x, y) --> (-x, -y) (This represents a 180-degree rotation around the origin.)

Front

What is the result of reflecting the point (3, -2) across the x-axis?

Back

(3, 2) (The y-coordinate changes sign.)

Front

Describe the translation that occurs in coordinate notation: (x, y) --> ?

Back

(x, y) --> (x - 4, y + 2) (This moves the point 4 units left and 2 units up.)

Front

What transformation occurs from point X (-1, 3) to X' (1, -3)?

Back

Rotation 180 degrees (This flips the point across both axes.)

Front

When translating (x - 4, y), how does the point move?

Back

4 units left (The x-coordinate decreases by 4.)

Front

What is the coordinate notation for a reflection across the y-axis?

Back

(x, y) --> (-x, y) (The x-coordinate changes sign.)

Front

What is the coordinate notation for a reflection across the x-axis?

Back

(x, y) --> (x, -y) (The y-coordinate changes sign.)

Front

What does a translation of (x + 2, y - 4) represent?

Back

Moves the point 2 units right and 4 units down.

Front

What is the effect of a 90-degree rotation counterclockwise on the point (x, y)?

Back

(x, y) --> (-y, x) (The coordinates switch places and the new x-coordinate is negated.)

Front

What is the effect of a 270-degree rotation counterclockwise on the point (x, y)?

Back

(x, y) --> (y, -x) (The coordinates switch places and the new y-coordinate is negated.)
