Term | Definition |
Auxiliary Line | A line drawn in a figure to aid in a proof. |
Congruent Polygons | Two polygons whose corresponding sides and angles are congruent. |
Corresponding Angles | Angles in the same position in two different polygons that have the same number of angles. |
Corresponding Sides | Sides in the same position in two different polygons that have the same number of sides. |
CPCTC | An abbreviation for the phrase "Corresponding Parts of Congruent Triangles are Congruent". It can be used as a justification in a proof after you have proven two triangles congruent. |
Included Angle | An angle formed by two adjacent sides of a polygon (aka an angle in-between two sides). |
Included Side | The common side of two consecutive angles in a polygon (aka a side in-between two angles). |
Side-Side-Side (SSS) Congruence Postulate | If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent. |
Side-Angle-Side (SAS) Congruence Postulate | If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. |
Angle-Side-Angle (ASA) Congruence Postulate | 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. |
Angle-Angle-Side (AAS) Congruence Theorem | If two angles and a nonincluded side of one traingle are congruent to the corresponding angles and nonincluded side of another triangle, then the triangles are congruent. |
Hypotenuse-Leg (HL) Congruence Theorem | If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent. |
Isosceles Triangle Theorem | If two sides of a triangle are congruent, then the angles opposite the sides are congruent. |
Converse of Isosceles Triangle Theorem | If two angles of a triangle are congruent, then the sides opposite those angles are congruent. |
Vertex Angle | The angle formed by the legs of an isosceles triangle. It is located across from the base. |
Base Angles | The two congruent angles of an isosceles triangle. The base is located between them. |
Base | The noncongruent side opposite the vertex angle. |
Legs | The two congruent sides of an isosceles triangle. The vertex angle is located between them. |
Equilateral Triangle Corollary | If a triangle is equilateral, then it is equiangular. |
Equiangular Triangle Corollary | If a triangle is equiangular, then it is equilateral. |
