Equilateral Triangles
Triangles with all sides congruent and all angles \(= 60^{\circ}\)

Practice Problems
\(\textbf{1)}\) \( \text{In the below equilateral triangle, solve for }x, y \text{ and }z.\)

\(x=7\) \(y=22\) \(z=55\)
\(\textbf{2)}\) \( \text{In the below equilateral triangle, solve for }x.\)

\(x=30\)
Challenge Problem
\(\textbf{3)}\) \( \text{In the below equilateral triangle, solve for }x.\)

The answer is \(x=2\)
\(\,\,\,\,\,x^2+3=4x-1\)
\(\,\,\,\,\,x^2-4x+4=0\)
\(\,\,\,\,\,(x-2)^2=0\)
\(\,\,\,\,\,x-2=0\)
\(\,\,\,\,\,x=2\)
