Okay i need the plan of proof then the statements and reasons in order Prove: If an isosceles triangle has an altitude from the vertex to the base, then the altitude bisects the vertex angle. In two-column proofs, the statements in the reason column are almost always defi nitions, postulates, or theorems. Not Used. In other words, we can't use the diagram of an equilateral triangle if we're trying to establish a property of isosceles triangles. Proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles. 0000006897 00000 n
