Geometry: Measurement of Angles (Level 5 of 9)

The video tutorial covers converting fractional degrees to degrees, minutes, and seconds (DMS) notation, converting DMS to decimal degrees, and performing addition and subtraction of angles in DMS format. It provides step-by-step examples for each type of conversion and operation, emphasizing the importance of handling fractional parts and borrowing techniques in subtraction.

How do you convert a fractional degree into minutes?

• Add 60 to the fraction

• Subtract 60 from the fraction

• Multiply the fraction by 60

• Divide the fraction by 60

What is the first step in converting degrees, minutes, and seconds to decimal degrees?

• Subtract minutes from degrees

• Multiply minutes by 60

• Divide minutes by 60

• Add minutes to degrees

When adding angles, what should you do if the seconds exceed 60?

• Ignore the excess seconds

• Subtract the excess seconds from minutes

• Add the excess seconds to degrees

• Convert excess seconds into minutes

In angle addition, what happens when the minutes exceed 60?

• Subtract the excess minutes from degrees

• Ignore the excess minutes

• Convert excess minutes into degrees

• Add the excess minutes to seconds

What is the first step in subtracting angles when the top seconds are less than the bottom seconds?

• Borrow a minute and convert it to seconds

• Add 60 seconds to the top seconds

• Subtract the bottom seconds from the top seconds

• Ignore the seconds and move to minutes

How do you handle a situation where the top minutes are less than the bottom minutes in subtraction?

• Subtract the bottom minutes from the top minutes

• Borrow a degree and convert it to minutes

• Add 60 minutes to the top minutes

• Ignore the minutes and move to degrees

What is the final result of subtracting 67 degrees 21 minutes 37 seconds from 90 degrees?

• 23 degrees 39 minutes 24 seconds

• 21 degrees 37 minutes 22 seconds

• 22 degrees 38 minutes 23 seconds

• 24 degrees 40 minutes 25 seconds
