7.2: Complementary & Supplementary Angles

7.2: Complementary & Supplementary Angles

Wednesday 3/17/21

Remember, adjacent angles are "next to" each other, in the sense that they share a common vertex and side, but don't overlap.

So, non-adjacent means that the angles are separate from each other and do not share a common vertex and side.

In the first examples, you will check if pairs of angles or complementary, supplementary, or neither depending on the sum of the angles.

Review the vocabulary, if needed. When you are ready, move on to the next slide.

Multiple Choice

Tell whether the angles are complementary, supplementary, or neither.

• complementary

• supplementary

• neither

In the next examples, you will write and solve equations to find the value of x. You did this yesterday too... so your equations will either add up to equal 90 or add up to equal 180.

This is the end of the lesson. Now, go to Google Classroom and open the assignment called Wed 3/17: 7.2 Practice. That assignment is due tomorrow at 8:30am.

If you have questions about the lesson, review the slides or come to the Zoom call to ask any questions you may have!
