1-4 Measuring Angles
![Page 2: 1-4 Measuring Angles](https://reader035.fdocuments.us/reader035/viewer/2022062720/568134ab550346895d9bbeef/html5/thumbnails/2.jpg)
When naming angle using three points, the vertex
must go in the middle.

Problem 2: Measuring and Classifying Angles
What at the measures of <LKN, <JKL, and <JKN? Classify each angle as acute, obtuse, or right, or straight.

Problem 2: Measuring and Classifying Angles
What at the measures of <LKH, <HKN, and <MKH? Classify each angle as acute, obtuse, or right, or straight.

Problem 3:
Using Congruent
Angles
Synchronized swimmers form angles with their bodies, as shown in the picture.
If m<ABC = 49, what is m<DEF?
If m<GHJ = 90, what is m<KLM?
