Exploring Angles on a Straight Line

What is the total sum of angles formed on a straight line?

• 90 degrees

• 360 degrees

• 180 degrees

• 270 degrees

What is the primary rule for angles on a straight line discussed in the video?

• They sum up to 90 degrees

• They sum up to 180 degrees

• They sum up to 270 degrees

• They sum up to 360 degrees

If one angle on a straight line is 100 degrees, what is the measure of the other angle?

• 80 degrees

• 100 degrees

• 70 degrees

• 90 degrees

In a scenario with two angles on a straight line where one is known, how do you find the unknown angle?

• Subtract the known angle from 180

• Add the known angle to 180

• Multiply the known angle by 2

• Subtract the known angle from 360

If the sum of two angles is 180 degrees, and one angle is 70 degrees, what is the other angle?

• 110 degrees

• 100 degrees

• 90 degrees

• 120 degrees

What is the value of angle Y if one angle is 50 degrees and another is 20 degrees on the same line?

• 110 degrees

• 100 degrees

• 120 degrees

• 90 degrees

How many angles are discussed in the second example?

• Three

• Four

• One

• Two

What is the correct way to calculate an unknown angle on a straight line?

• Multiply each known angle by two and subtract from 180

• Add up all angles and divide by the number of angles

• Subtract known angles from 180

• Add up known angles and subtract from 360

If three angles on a straight line are 50 degrees, 20 degrees, and an unknown angle, what is the unknown angle?

• 120 degrees

• 110 degrees

• 100 degrees

• 90 degrees
