Exploring Adjacent Angles in 7th Grade Math

The video tutorial covers adjacent angles, focusing on complementary and supplementary angles. Complementary angles sum to 90 degrees and form a right angle, while supplementary angles sum to 180 degrees and form a straight angle. The tutorial explains how to calculate unknown angles when given one angle in a complementary or supplementary pair. It concludes with a recap of the learning goals, emphasizing the ability to recognize and calculate these angles.

What is the total degree measure that complementary angles sum up to?

• 360 degrees

• 90 degrees

• 45 degrees

• 180 degrees

If two angles are adjacent and complementary, what geometric shape do they form?

• Circle

• Right angle

• Straight line

• Acute angle

What mnemonic helps remember that complementary angles add up to 90 degrees?

• They are always acute

• They complete a circle

• They form a straight line

• They complement each other

What is the sum of the measures of supplementary angles?

• 360 degrees

• 270 degrees

• 180 degrees

• 90 degrees

What type of angle is formed when two supplementary angles are adjacent?

• Straight angle

• Acute angle

• Right angle

• Obtuse angle

Which of the following is NOT true about supplementary angles?

• They start with the letter 'S'

• They can form a straight angle when adjacent

• They always form a right angle when adjacent

• They add up to 180 degrees

If one angle measures 70 degrees, what is the measure of its complementary angle?

• 20 degrees

• 90 degrees

• 180 degrees

• 110 degrees

How do you find the measure of the unknown angle if it is supplementary to another known angle?

• Divide the known angle by 2

• Multiply the known angle by 2

• Subtract the known angle from 180

• Add 90 to the known angle

What should you subtract from 180 to find the supplement of a 120-degree angle?

• 180 degrees

• 120 degrees

• 90 degrees

• 60 degrees
