4-1 Congruent Figures
Congruent figures have same size and shape When 2 figures are congruent you can slide, flip, or turn one so that it fits exactly on the other one
Congruent Figures Congruent Polygons: Have congruent corresponding parts – matching sides and angles. When naming congruent polygons you must list corresponding vertices in the same order
Problem 1: Finding Congruent Parts
Problem 2: Using Congruent Parts The wings of an SR-71 Blackbird aircraft suggest congruent triangles. What is m<D?
Problem 3: Finding Congruent Triangles Are the triangles congruent? Justify your answer.
Third Angles Theorem If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent
Problem 4: Proving Triangles Congruent
Congruent Figures Section 4-1. Solve each equation. 1.x + 6 = 252.x = x = 5404.x + 10 = 2x 5.For the triangle at the right, use the Triangle.
4.1 Congruent Figures Chapter 4 Congruent Triangles.
Congruent Figures Congruent Polygons have congruent corresponding parts- their matching sides and angles.
Congruent Triangles Congruent Triangles – Triangles that are the same size and same shape. ABC is congruent to DEF, therefore: A cong. to Dseg.
4-1 Congruent Figures. Congruent Figures Whenever two figures have the same size and shape, they are called Congruent. We already know about congruent.
Congruent Polygons. Congruent segments have the same length.
Congruent Polygons and Corresponding Parts Objective: to name corresponding parts of congruent polygons and write congruence statements for congruent figures.
Congruent and Similar. Similar and Congruent Figures Congruent polygons have all sides congruent and all angles congruent. Similar polygons have the same.
3-1: Congruent Figures Honors Geometry.
Chapter 4: Congruent Triangles Lesson 4-4: Using Congruent Triangles: CPCTC Goal: Use triangle congruence and CPCTC to prove that parts of two congruent.
I can identify corresponding angles and corresponding sides in triangles and prove that triangles are congruent based on CPCTC.
4.1: CONGRUENT FIGURES Objectives: To recognize congruent figures and their corresponding parts.

Congruent Triangles Geometry Chapter 4.
L.E.Q. How do you identify congruent figures and their corresponding parts?
Figures are congruent if you can slide, flip or turn them. If you know that two triangles are congruent then you can list their congruent sides and.
