What could be the measure of the third side? Find the measure of each side of equilateral triangle RST with RS = 2x + 2, ST = 3x, and TR + 5x - 4.
Can a right triangle be equilateral? | Homework.Study.com
Equilateral Triangles: In geometry, an equilateral triangle is defined as a triangle that has all sides of equal length. Another property that all equilateral triangles satisfy is that the measure of their angles are all equal and have a measure of 60°. We can use this property to determine if a given triangle is equilateral or not.
