6. Describing Pairs of Angles

Continue to next subchapter

Exercise 30 Page 429

You will need a protractor.

Example Solution:

Practice makes perfect

Adjacent angles are two angles that have a common vertex and share a side. The two angles we want to create are 45^(∘) and 97^(∘) so that together they have a measure of 45^(∘)+97^(∘)=142^(∘). Using a protractor, we can draw this angle.

Next, we will use a protractor to draw either 97^(∘) or a 45^(∘) angle in the interior of the 142^(∘) angle.

Let's clean up the diagram

We have now constructed a pair of adjacent angles that have angle measures of 45^(∘) and 97^(∘).
