Term
Triangle Sum Conjecture
Definition
The sum of the measures of the angles in every triangle is 180 degrees.
Term
Isosceles Triangle Conjecture
Definition
If a triangle is isosceles, then its base angles are congruent.
Term
Converse Isosceles Triangle Conjecture
Definition
If a triangle has two congruent angles, then its an isosceles triangle.
Term
Triangle Inequality Conjecture
Definition
The sum of the lengths of any two sides of a triangle is greater than the length of the third one.
Term
Side-Angle Inequality Conjecture
Definition
In a triangle, if one side is longer than another side, then the angle opposite the longer side is larger.
Term
Triangle Exterior Angle Conjecture
Definition
The measure of an exterior angle of a triangle is equal to the sum of the remote interior angles.
Term
SSS Congruence Conjecture
Definition
If three sides of one angle are congruent to the three sides of another triangle, then the two triangles are congruent.
Term
SAS Congruence Conjecture
Definition
If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
Term
ASA Congruence Conjecture
Definition
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
Term
SAA Congruence Conjecture
Definition
If two angles and a non-included side of one triangle are congruent to the corresponding angles and side of another triangle, then the triangles are congruent.
Term
Vertex Angle Bisector Conjecture
Definition
In an isosceles triangle, the bisector of the vertex angle is also the median and the altitude to the base.
Term
Equilateral/Equiangular Triangular Conjecture
Definition
Every equilateral triangle is equiangular, and, conversely, every equiangular triangle is equilateral.
