Name
To set up the problem you must:
1.
2.
3.
Examples:
1.
If two altitudes of a triangle are congruent, then the triangle is isosceles.
2.
The medians of a triangle are congruent if the triangle is equilateral.
3.
The altitude to the base of an isosceles triangle bisects the vertex angle.
4.
If two angles of one triangle are congruent to two angles of another triangle, the
remaining pair of angles are also congruent.
5.
If two triangles are congruent, then a pair of corresponding medians are congruent.
6.
The angle bisectors of the base angles of an isosceles triangle meet to form another
isosceles triangle with the base.
7.
The line segments joining the vertex angle of an isosceles triangle to the trisection
points of the base are congruent.
