1) How many different isosceles triangles can you find that have sides that are whole-number lengths and that have a perimeter of \(21\)?
2) Given: \(\overline{AB}\) and \(\overline{AC}\) are legs of isosceles \(\triangle ABC\)
\(m\angle 1 = 7x\)
\(m\angle 3 = 2x + 18\)
Find: \(m\angle 2\)
2) Given: \(\overline{AB}\) and \(\overline{AC}\) are legs of isosceles \(\triangle ABC\)
\(m\angle 1 = 7x\)
\(m\angle 3 = 2x + 18\)

3) If \(\triangle XYZ\) is isosceles and its perimeter is less than \(100\), which side of \(\triangle XYZ\) is the base?
4) Given \(\triangle ABC\) is equilateral. What are the values of \(x\) and \(y\)?
6) \(\triangle ABC\) is isosceles with \(AB = x^2 + 1, BC = 4x – 2,\)and \(AC = 2x + 4\). Solve for \(x\). Is \(\triangle ABC\) equilateral?
