Understanding Angles with a Protractor

If a ray starts at 20 degrees, where should the second ray be placed to form a 120-degree angle?

• At 140 degrees

• At 40 degrees

• At 160 degrees

• At 180 degrees

What is the angle type if the second ray is placed at 140 degrees when starting from 20 degrees?

• Obtuse

• Right

• Acute

• Straight

When starting from 120 degrees, which position will form a 40-degree angle by moving in the opposite direction?

• 80 degrees

• 100 degrees

• 160 degrees

• 200 degrees

To create a 110-degree angle from a 50-degree starting point, which point should the second ray pass through?

• Point A at 110 degrees

• Point B at 130 degrees

• Point D at 180 degrees

• Point C at 160 degrees

If a ray is at 50 degrees, what is the distance needed to form a 110-degree angle?

• 60 degrees

• 110 degrees

• 160 degrees

• 180 degrees
