Supplementary and Complementary Angles

This video tutorial covers advanced concepts of angles, including the angle addition postulate, complementary and supplementary angles, and opposite and adjacent angles. It explains how to calculate unknown angles using these principles and provides examples to illustrate each concept.

What is the result when angle ACB is added to angle BCD?

• Angle BCA

• Angle ABD

• Angle ACD

• Angle ABC

What is the angle addition postulate?

• The sum of two angles is equal to the larger angle they form.

• The sum of two angles is always 90 degrees.

• The sum of two angles is equal to the smaller angle they form.

• The sum of two angles is always 180 degrees.

What do complementary angles add up to?

• 360 degrees

• 180 degrees

• 45 degrees

• 90 degrees

If one angle in a complementary pair is 33 degrees, what is the measure of the other angle?

• 37 degrees

What is the measure of angle ABD if angle DBC is 52 degrees and they are complementary?

• 48 degrees

• 28 degrees

• 58 degrees

• 38 degrees

What do supplementary angles add up to?

• 360 degrees

• 180 degrees

What is the measure of the other angle if one angle in a supplementary pair is 90 degrees?

• 70 degrees

• 100 degrees

• 90 degrees

• 80 degrees

What are opposite angles?

• Angles that are next to each other

• Angles that add up to 180 degrees

• Angles that add up to 90 degrees

• Angles that are opposite each other

Which of the following is true about adjacent angles?

• They are always equal.

• They are always complementary.

• They are always supplementary.

• They share a common side and vertex.
