What type of angle is formed when two lines intersect at a point and one of the angles formed is 90 degrees?

• Acute angle

• Obtuse angle

• Right angle

• Straight angle

Which of the following is NOT a type of line?

• Parallel lines

• Perpendicular lines

• Intersecting lines

• Curved lines

Which of the following statements is true for two lines that are perpendicular to each other?

• They intersect at an acute angle.

• They do not intersect.

• They intersect at a 90-degree angle.

• They are always horizontal.

What type of angle is less than 90 degrees?

• Acute angle

• Obtuse angle

• Right angle

• Reflex angle

Which of the following properties is NOT true for parallel lines?

• They are always the same distance apart.

• They never intersect.

• They intersect at a 90-degree angle.

• They may be extended infinitely in both directions without ever meeting.

How can you identify parallel lines in a given figure?

• By finding lines that intersect at any angle

• By finding lines that intersect at a 90-degree angle

• By finding lines that do not intersect and are equidistant

• By finding lines that curve and never meet

What is the measure of each angle formed by perpendicular lines?

• 45 degrees

• 90 degrees

• 180 degrees

• 360 degrees

Which of the following angles is an obtuse angle?

• 45 degrees

• 90 degrees

• 120 degrees

• 180 degrees

When two lines are cut by a transversal, which of the following is NOT a property of the corresponding angles?

• They are equal in measure.

• They are on the same side of the transversal.

• They are on opposite sides of the transversal.

• They are on the same side of the two lines.
