Geometry, Semester 1, Review

Front

What is a reflection in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

Define complementary angles.

Back

Two angles whose measures add up to 90 degrees.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

What is a 90 degrees clockwise rotation?

Back

A transformation that turns a figure 90 degrees to the right around a point.

Front

What is a 180 degrees rotation about the origin?

Back

A transformation that turns a point to the opposite quadrant, changing both coordinates' signs.

Front

Define supplementary angles.

Back

Two angles whose measures add up to 180 degrees.

Front

What is a linear pair of angles?

Back

Two adjacent angles that form a straight line, summing to 180 degrees.

Front

What is the significance of vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What does it mean to rotate a point in the coordinate plane?

Back

To turn the point around a fixed point (usually the origin) by a specified angle.

Front

What is the relationship between angle 2 and angle 6 if they are corresponding angles?

Back

They are equal in measure when two parallel lines are cut by a transversal.
