Exploring Vertical Angles in Geometry

What is a key characteristic of vertical angles?

• They are formed by parallel lines.

• They are formed by intersecting lines or line segments.

• They are always supplementary.

• They are always right angles.

Where do vertical angles share a common point?

• At the center of a circle.

• At the endpoint of one line.

• At the intersection of the lines.

• At the midpoint of the line segment.

What is the most important property of vertical angles?

• They are always obtuse.

• They are always acute.

• They are always congruent.

• They are always complementary.

In a diagram with two intersecting lines, which angles are vertical angles?

• Angles 1 and 2

• Angles 1 and 3

• Angles 2 and 3

• Angles 2 and 5

If angle 1 is congruent to angle 3, what can be said about these angles?

• They are complementary angles.

• They are supplementary angles.

• They are vertical angles.

• They are adjacent angles.

Which pair of angles is congruent if angles 2 and 4 are vertical angles?

• Angle 2 and angle 3

• Angle 1 and angle 2
