Exercise 1 Page 542

Use a dynamic geometry program, such as Geogebra, or a graphing calculator.

Side Lengths: 5 units
Angle Measures: 60^(∘)

Practice makes perfect

We will use a geometry software to draw a polygon with the following vertices. A(0,2),B(3,- 1), C(4,3) Let's start by entering these points into the software.

Now, if we look at the three points, we can see that they can form a triangle. We can use the geometry software to form a polygon by connecting the given points. After that, we will calculate each of the side lengths.

Because the side lengths of the triangle are all the same, we know that the triangle is equilateral. In an equilateral triangle, all of the angles are congruent as well. Just to make sure, we will let the program calculate it for us.

The measure of each of the angles is 60^(∘).
