Geometry: Chapter 5: Triangles and Congruence
Halvorsen
Chapter Five Objectives:
Section 1: Classifying Triangles
Learn to identify the parts of triangles and to classify triangles by their parts.
Vocabulary: triangle, vertex, equilateral, isosceles, and scalene.
Section 2: Angles of a Triangle
Learn to use the Angle Sum Theorem.
Vocabulary: equilateral triangle.
Section 3: Geometry in Motion
Learn to identify translations, reflections, and rotations and their corresponding parts.
Vocabulary: translation, reflection, rotation, transformation, preimage, isometry, image, and
mapping.
Section 4: Congruent Triangles
Learn to identify corresponding parts of congruent triangles.
Vocabulary: congruent triangles, corresponding parts.
Section 5: SSS and SAS
Learn to use the SSS and SAS tests for congruence.
Vocabulary: included angle.
Section 6: ASA and AAS
Learn to use the ASA and AAS tests for congruence.
Vocabulary: included side.
Chapter 5 Alignment to Core Standards:
Domain G.CO.A.4: Develop definitions of rotations, reflections, and translations in terms of angles,
circles, perpendicular lines, parallel lines, and line segments.
Domain G.CO.B.7: Use the definition of congruence in terms of rigid motions to show that two triangles
are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are
congruent.
Domain G.CO.B.8: Explain how the criteria for triangle congruence follow from the definition of
congruence in terms of rigid motions.
Domain G.CO.C.10: Prove theorems about triangles.
Domain G.CO.12: Make geometric constructions.
