Front

If G is the midpoint of segment FH, what is FG if FH = 30?

Back

FG = 15

Front

What is the contrapositive of the statement: "If a shape is a trapezoid, then it has exactly 1 pair of parallel sides."?

Back

If a shape does not have exactly 1 pair of parallel sides, then it is not a trapezoid.

Front

What can be said about the lines represented by the equations y = 3x + 2 and y = 3x - 3?

Back

The lines are parallel.

Front

Front

Define a midpoint in geometry.

Back

A midpoint is a point that divides a segment into two equal parts.

Front

What is the definition of a contrapositive in logic?

Back

The contrapositive of a statement is formed by negating both the hypothesis and conclusion and reversing them.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

If the slope of a line is 2, what is the slope of a line perpendicular to it?

Back
