### Step-by-Step Solutions for 7.1 Practice A Geometry Problems

1. Problem: Find the measure of angle A in the triangle below.

Solution: In a triangle, the sum of the interior angles is always 180 degrees. Since we already know the measures of angles B and C (40 degrees and 80 degrees, respectively), we can subtract their sum from 180 to find the measure of angle A. Therefore, angle A = 180 – 40 – 80 = 60 degrees.

2. Problem: Determine the type of quadrilateral represented by the figure below.

Solution: By examining the given figure, we can see that all four sides are equal in length. Additionally, opposite angles are congruent. These characteristics indicate that the quadrilateral is a rhombus.

3. Problem: Calculate the circumference of a circle with a radius of 5 centimeters.

Solution: The formula for the circumference of a circle is C = 2πr, where r represents the radius of the circle. Plugging in the given radius of 5 centimeters into the formula, we get C = 2π(5) = 10π centimeters.

### Conclusion

Mastering Geometry requires practice and understanding of various concepts. The step-by-step solutions provided for the 7.1 Practice A Geometry problems in this article can serve as a valuable resource for students. By carefully working through these solutions, students can enhance their problem-solving skills and develop a deeper comprehension of Geometry. Remember, practice makes perfect, so be sure to apply these solutions to similar problems to solidify your understanding of the subject.
