Vocabulary The two congruent sides of an isosceles triangle form this.

Vocabulary What is the vertex angle? HOME

Vocabulary If you know that two triangles are congruent, then the corresponding sides and angles of the triangles are congruent because of this.

Vocabulary What is CPCTC? HOME

Vocabulary The angles of an isosceles triangle that are not the vertex angle are called this.

Vocabulary What are the base angles? HOME

Vocabulary A this to a theorem is a statement that follows immediately from the theorem.

Vocabulary What is a corollary? HOME

Vocabulary These polygons have congruent corresponding parts.

Vocabulary What is congruent? HOME

Triangle Congruence These triangles are congruent by this postulate.

Triangle Congruence What is SSS? HOME

Triangle Congruence These triangles are congruent by this postulate.

Triangle Congruence What is SAS? HOME

Triangle Congruence These triangles are congruent by this theorem.

Triangle Congruence What is AAS? HOME

Triangle Congruence These triangles are congruent by this postulate.

Triangle Congruence What is ASA? HOME

Triangle Congruence These triangles are congruent by this theorem.

Triangle Congruence What is the HL Theorem? HOME

CPCTC CPCTC stands for this.

CPCTC What is corresponding parts of congruent triangles are congruent? HOME

CPCTC This is how CPCTC is used in proofs.

CPCTC What is prove two triangles congruent and then you can prove parts of the triangles are congruent? HOME

HOME

Isosceles and Equilateral Triangles This theorem says if 2 sides of a triangle are congruent, then the angles opposite those sides are congruent.

Isosceles and Equilateral Triangles What is the Isosceles Triangle Theorem? HOME

Isosceles and Equilateral Triangles If a triangle is equilateral, then the triangle is this.

Isosceles and Equilateral Triangles What is equiangular? HOME

Isosceles and Equilateral Triangles This theorem says if two angles of a triangle are congruent, then the sides opposite the angles are congruent.

Isosceles and Equilateral Triangles What is the Converse of Isosceles Triangle Theorem? HOME

Isosceles and Equilateral Triangles The bisector of the vertex angle of an isosceles triangle is the this of the base.

Isosceles and Equilateral Triangles What is perpendicular bisector? HOME

Isosceles and Equilateral Triangles If a triangle is equiangular, then the triangle is this.

Isosceles and Equilateral Triangles What is equilateral? HOME

Right Triangles This theorem says if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.

Right Triangles What is Hypotenuse-Leg Theorem? HOME

Right Triangles What additional information do you need to prove the triangles congruent by the HL theorem? T R L K B Q

Right Triangles What is angles T and Q are right angles and LT=KQ or BT=RQ? HOME
