Unit 1 Mid

Front

What is the color that is typically associated with the correct reflection in geometry?

Back

Red

Front

How do you translate a figure using a vector?

Back

To translate a figure, you move every point of the figure in the same direction and by the same distance as indicated by the vector.

Front

What does it mean to rotate a figure 120° counterclockwise?

Back

To rotate a figure 120° counterclockwise means to turn the figure around a point (like point C) in a circular motion, moving it 120° in the opposite direction of the clock's hands.

Front

What is a vector in geometry?

Back

A vector is a quantity that has both magnitude and direction, often represented as an arrow.

Front

What is the significance of point C in a rotation?

Back

Point C is the center of rotation; it remains fixed while the rest of the figure rotates around it.

Front

How do you determine the image of a figure after rotation?

Back

To determine the image of a figure after rotation, you can use a protractor to measure the angle of rotation from the center point.

Front

What is the difference between translation and rotation?

Back

Translation moves a figure without changing its orientation, while rotation turns a figure around a point.

Front

What is the formula for translating a point (x, y) by a vector (a, b)?

Back

The new coordinates after translation are (x + a, y + b).

Front

What is the effect of rotating a figure 90° counterclockwise?

Back

The coordinates of a point (x, y) become (-y, x) after a 90° counterclockwise rotation.

Front

What is the purpose of using colors in geometric transformations?

Back

Colors can help differentiate between various transformations and make it easier to visualize the changes.
