CL - Geom. - Mod. 1 - Topic 2 Test

Front

What is the result of reflecting a point over the y-axis?

Back

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

Front

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

Back

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

Front

What are congruent line segments?

Back

Line segments that have the same length.

Front

What is the effect of rotating a point 180 degrees about the origin?

Back

The coordinates of the point change from (x, y) to (-x, -y).

Front

What is the sequence of transformations to map \( \Delta ABC \) to \( \Delta DEF \)?

Back

Rotate 180 degrees about the origin, then translate left 2 units.

Front

How do you represent reflecting a shape over the x-axis and then translating it up 2 units and right 5 units?

Back

The algebraic representation is \( (x+5, -y+2) \).

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a point, while reflection flips a shape over a line.

Front

What is the coordinate transformation for a point (x, y) after a translation of 4 units to the right?

Back

The new coordinates will be (x+4, y).
