Parts of an Isosceles Triangle
In an isosceles triangle, the congruent sides are called [color=#6aa84f]LEGS [/color]. The third side is called the [color=#0000ff]BASE[/color]. [br]The angle between the legs and opposite the base is called the [color=#ff0000]VERTEX ANGLE[/color]. The other two angles are called [color=#0000ff]BASE ANGLES[/color]. [br]
Name the base angles
Name the vertex angle
Name the legs
Name the base
Drag the vertices of the triangle and observe the angle measures. What do you notice? Write a conjecture
