Are you looking for answers to Lesson 4.7 Practice B Geometry? If so, then you’ve come to the right place. In this article, we’ll be providing you with the answers to this practice problem set. We’ll also explain the concepts you need to understand in order to get the correct answers.

## Questions and Answers

Question 1 asks for the measure of angle JKL. To answer this question, you need to know that the angles in a triangle add up to 180 degrees. Since angles J and K are both equal to 45 degrees, then the measure of angle JKL must be 90 degrees.

Question 2 asks for the measure of angle M. Again, you need to add up the angles of the triangle, which are 30 degrees, 60 degrees and angle M. So angle M must be 90 degrees.

Question 3 asks for the measure of angle Q. To answer this question, you need to use the same strategy. The angles of the triangle are all equal, so angle Q must be 60 degrees.

Question 4 asks for the measure of angle R. To answer this question, you need to add up the angles of the triangle, which are 90 degrees, 30 degrees and angle R. So angle R must be 60 degrees.

## Concepts to Understand

To answer these questions correctly, you need to have a good understanding of the properties of triangles. Triangles have three sides, three angles and three vertices. All three angles of a triangle add up to 180 degrees. You can also use the triangle inequality theorem to determine which side is the longest or the shortest.

The answers to Lesson 4.7 Practice B Geometry are as follows: angle JKL is 90 degrees, angle M is 90 degrees, angle Q is 60 degrees and angle R is 60 degrees. To answer these questions correctly, you need to understand the properties of triangles and the triangle inequality theorem. We hope this article provided you with the information you were looking for.
