Can vertical angles be supplementary

The video tutorial covers the concepts of complementary, supplementary, and vertical angles. It explains how vertical angles are formed by intersecting lines and discusses whether they can be supplementary. The tutorial also explores linear pairs, right angles, and introduces perpendicular lines, emphasizing their properties and relationships in geometry.

What is the main characteristic of supplementary angles?

• They add up to 90 degrees.

• They are always equal.

• They add up to 180 degrees.

• They are always different.

How are vertical angles formed?

• By parallel lines.

• By intersecting lines.

• By perpendicular lines.

• By adjacent lines.

If two angles are vertical and supplementary, what is their measure?

• 180 degrees each.

• 90 degrees each.

• 60 degrees each.

• 45 degrees each.

What is a linear pair of angles?

• Two angles that are equal.

• Two angles that add up to 90 degrees.

• Two angles that share a common side and add up to 180 degrees.

• Two angles that are opposite each other.

What is the measure of angle 5 if angle 4 is 90 degrees and they form a linear pair?

• 60 degrees

• 180 degrees

• 90 degrees

• 45 degrees

What do we call lines that intersect to form right angles?

• Vertical lines

• Linear lines

• Parallel lines

• Perpendicular lines

What is the sum of angles around a point?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees
