Question

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

Chapter 10.1, Problem 1E

To determine

To find the angle measure and classify the triangle.

Expert Solution & Answer

Answer to Problem 1E

The measure of all the angles measure is 60∘

The triangle is an equilateral triangle

Explanation of Solution

Given information:

Ratio of a triangle is 1:1:1

Formula Used: Sum of all angles of a triangle is 180∘

Calculation:

The sum of all the angles of a triangle is 180∘

Let X be the angle of a triangle

x+x+x=180∘

This gives us −

3x=180∘

Dividing both sides by3

x=180∘3

Hence, Final value of x=60∘

Conclusion- The angle measures 60∘

Since all the angles of the triangle are same it is an equilateral triangle.
