Geometry is a branch of mathematics that focuses on shapes, angles, and sizes. It is an important subject that must be understood and mastered in order to pass tests, complete assignments, and solve problems. Lesson 11.7 Practice A is a geometry exercise that helps students gain a better understanding of the subject. Here are the answers to the questions in the exercise.

## Question 1

The answer to Question 1 is an acute triangle. An acute triangle is a triangle with three angles that measure less than 90 degrees. All three angles in an acute triangle are less than 90 degrees, and the sum of the angles is equal to 180 degrees.

## Question 2

The answer to Question 2 is a right triangle. A right triangle is a triangle with one angle that measures exactly 90 degrees. The other two angles in a right triangle are acute angles, and their sum is equal to 90 degrees.

## Question 3

The answer to Question 3 is an obtuse triangle. An obtuse triangle is a triangle with one angle that measures more than 90 degrees. The other two angles in an obtuse triangle are acute angles, and their sum is equal to 180 degrees.

## Question 4

The answer to Question 4 is a scalene triangle. A scalene triangle is a triangle with three sides of different lengths and three angles of different sizes. The sum of the angles of a scalene triangle is equal to 180 degrees.

Lesson 11.7 Practice A is a great geometry exercise for students to practice and gain a better understanding of the subject. By understanding the answers to the questions in the exercise, students can build a strong foundation of knowledge in geometry and be better prepared for future assignments and tests.
