Geometry Final Exam Part 2

Front

What does the symbol \( \overline{AB} \) represent?

Back

Segment AB

Front

What is the slope of a line perpendicular to the line \( y = -2x - 3 \)?

Back

1/2

Front

What is a perpendicular bisector?

Back

A line that divides a segment into two equal parts at a 90-degree angle.

Front

What is rotational symmetry?

Back

A figure has rotational symmetry if it can be rotated around a central point and still look the same.

Front

Define a median in a triangle.

Back

A segment from a vertex to the midpoint of the opposite side.

Front

What is an angle bisector?

Back

A ray that divides an angle into two equal angles.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is the formula for the slope of a line?

Back

Slope (m) = \( \frac{{y_2 - y_1}}{{x_2 - x_1}} \) for points (x1, y1) and (x2, y2).

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

What is the distance formula in a coordinate plane?

Back

Distance = \( \sqrt{{(x_2 - x_1)^2 + (y_2 - y_1)^2}} \) for points (x1, y1) and (x2, y2).
