Exploring Supplementary Angles and Their Relationships

The video tutorial by Mr. J covers the concept of supplementary angles, which are two angles that add up to 180 degrees, forming a straight line. The tutorial includes examples where one angle is given, and the other is missing, demonstrating how to calculate the missing angle by subtracting the given angle from 180 degrees. The video emphasizes the importance of double-checking calculations to ensure accuracy. The tutorial concludes with a recap of the key points discussed.

What is the total of supplementary angles in degrees?

• 90 degrees

• 135 degrees

• 115 degrees

If angle ABD is found to be 115 degrees, what was the given angle?

• 75 degrees

• 95 degrees

• 65 degrees

How do you verify the correctness of a found supplementary angle?

• Subtract it from 360 degrees

• Add it to the given angle and check if it equals 180 degrees

• Divide it by 2

• Multiply it by 2

After finding a supplementary angle, what should you do next?

• Start a new problem

Why are supplementary angles important in geometry?

• They are always equal

• They can only be acute angles

• They form a circle

• They add up to 180 degrees and form a straight line
