Given the triangle shown in the picture, you can identify that:
- It has three congruent angles (they have the same measure):
[tex]60\text{\degree}[/tex]- Its three sides have the same length:
[tex]5.7\text{ }units[/tex]In order to solve this exercise you need to remember that, by definition:
- A Isosceles Triangle has two sides that have the same length and two congruent angles.
- An Equilateral Triangle is a triangle whose sides have all the same lengths and its interior angles have the same measure.
- A Right Triangle has an angle that measures 90 degrees.
- A Scalene Triangle has three sides of different lengths.
- An Acute Triangle whose angles measure less than 90 degrees.
Therefore, you can conclude that the given triangle is an Equilateral Triangle.
Hence, the answer is: Second option.
