Congruent Triangles – Pairs of Triangles Page 11
We will be proving one pair of triangles congruent to help us prove a second pair of triangles congruent!

1Geometry Lesson: Congruent Polygons, Triangles, SAS Aim: What are congruent polygons? How do we prove triangles congruent using Side-Angle-Side Postulate?
Chapter 4.6 Notes: Use Congruent Triangles Goal: You will use congruent triangles to prove that corresponding parts are congruent.
3-1: Congruent Figures Honors Geometry.
I can identify corresponding angles and corresponding sides in triangles and prove that triangles are congruent based on CPCTC.
Congruent Triangles – Overlapping Triangles
TODAY IN GEOMETRY… Review: Finding congruent angles and sides and proving triangles are congruent. Learning Goal: 4.6 Use CPCTC to prove congruent.
Proving Lines Perpendicular Page 4. To prove lines perpendicular: 12 Prove: Given: s t StatementReason 1. Given 2. Two intersecting lines that form congruent.

TEQ – Typical Exam Questions. J Q P M K L O Given: JKLM is a parallelogram Prove: StatementReason 2. Given 1. Given1. JKLM is a parallelogram 3. Opposite.
Similar Triangle Proofs Page 5-7. A CB HF E Similar Triangle Proof Notes To prove two triangles are similar, you only need to prove that 2 corresponding.
4.3 Proving Triangles are Congruent Side-Side-SideSide-Angle-Side.
StatementReason 1. Given 2. Chords that intercept congruent arcs are congruent Example 1 3. All radii of a circle are congruent.
Remember : Reason: An exterior angle of a triangle is greater than either of its nonadjacent interior angles and and Exterior angle theorem.
