... This definition implies that any equilateral triangle is isosceles too, but there are isosceles triangles that are not equilateral. In any isosceles triangle, the angles opposite to the congruent sides are also congruent. In fact, this condition could be used to give an alternate definition of isosc ...

... By the Exterior Angle Inequality Theorem, m14 > m4 and m14 > m11. In addition, m14 > m2 and m14 > m4 + m3, so m14 > m4 and m14 > m3. Since 11 and 9 are vertical angles, they have equal measure, so m14 > m9. m9 > m6 and m9 > m7, so m14 > m6 and m14 > m7. ...
