Determining the Conditions under which Lines and Segments are

Tell whether each statement is true or false.

Parallel lines are coplanar lines that do not intersect.

• TRUE

• FALSE

Two intersecting are always perpendicular.

• TRUE

• FALSE

If two parallel lines are cut by a transversal and a pair of alternate interior angles are supplementary, then the transversal is perpendicular to the two parallel lines.

• TRUE

• FALSE

Line 1 is a transversal if it intersects two coplanar lines and 3 at the same point/s.

• TRUE

• FALSE

If two lines are cut by a transversal and a pair of alternate interior angles are congruent, then the lines are parallel.

• TRUE

• FALSE

If a transversal is perpendicular to two parallel lines, then the interior angles on the same side of the transversal are congruent.

• TRUE

• FALSE

If a line is the perpendicular bisector of a line segment, then the line intersects the segment at any point.

• TRUE

• FALSE

If the angles in a linear pair are congruent, then the lines containing their sides are perpendicular.

• TRUE

• FALSE

If two coplanar lines are perpendicular to a third line, then the two coplanar lines are perpendicular to each other.

• TRUE

• FALSE

If two coplanar lines are perpendicular to a third line, then the two coplanar lines are perpendicular to each other.

• TRUE

• FALSE
