What condition must be met for lines l and m to be considered parallel in the context of alternate angles?

Pairs of alternate angles are equal (∠3 = ∠5, ∠1 = ∠7)

Fill in the blank: The sum of the interior angles on the same side of the transversal is ______.

180°

True or False: Corresponding angles must be equal for lines to be parallel.

True.

Riddle: I am a line that divides another into two equal parts, but I do not touch the ends. What am I?

A perpendicular bisector.

Which of the following statements is true when two lines are parallel? A) ∠2 = ∠4 B) ∠1 + ∠6 = 180° C) ∠3 = ∠5 D) All of the above

D) All of the above

Fill in the blank: To draw an angle bisector, you must first draw an arc with ______ as the center.

P

True or False: The angle bisector divides an angle into two equal parts.

True.

What must be done after drawing arcs from both points when constructing a perpendicular bisector?

Join the intersection points of the arcs.

Riddle: I am created by two rays originating from the same point, creating a space between me. What am I?

An angle.

In the construction of a perpendicular bisector, what is the relationship between the radius and segment AB?

The radius must be more than half of AB.

Which angles are equal if lines l and m are parallel and ∠2 is given? A) ∠6 B) ∠8 C) ∠3 D) ∠1

A) ∠6

Fill in the blank: The angles on the same side of the transversal that add up to 180° are known as ______ angles.

Consecutive interior

True or False: A perpendicular bisector can be drawn using any radius.

False. The radius must be more than half of the segment being bisected.

What is the first step in drawing an angle bisector?

Draw an arc with P as the center.

Riddle: I can be measured and divided, but I cannot be seen; I shape the world around you. What am I?

An angle.

Identify the condition that indicates lines l and m are parallel using corresponding angles.

Pairs of corresponding angles are equal (∠2 = ∠6, ∠4 = ∠8).

Fill in the blank: The angles formed on the opposite sides of the transversal and inside the two lines are called ______ angles.

Alternate interior

True or False: The method of constructing a perpendicular bisector involves using two different radii.

False. The same radius is used for both points.

What is the significance of ∠3 + ∠6 = 180° in relation to parallel lines?

It indicates that the lines are parallel if this condition is satisfied.

Which construction method is used to create a line that divides an angle into two equal angles?

Drawing an angle bisector.
