Section 4-3: Congruent Triangles By the end of this lesson, you should be able to answer: • How do you name and use corresponding parts of congruent polygons? • How do you prove triangles congruent using the definition of congruence? Vocabulary: Congruent Congruent Polygons Corresponding Parts Theorem 4.3 - Third Angles Theorem Theorem 3 : Hypotenuse-Acute (HA) Angle Theorem. If the hypotenuse and an acute angle of a right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent. Identifying Congruent Triangles Can the triangles be proven congruent with the information given in the diagram? If so, state the theorem you would use. a. b. c. SOLUTION a. The vertical angles are congruent, so two pairs of angles and a pair of non-included sides are congruent. The triangles are congruent by the AAS Congruence Theorem. b.

Find each angle measure. 8. m∠G 9. m∠D Reason for statement 4: Given. Statement 5: Reason for statement 5: Given. Statement 6: Reason for statement 6: If two angles are congruent (angles SNW and TOA), then their Like Multiples are congruent (twice one equals twice the other). Statement 7: Reason for statement 7: ASA (using line 1, 3, and 6) Reteach Congruent Triangles Triangles are congruent if they have the same size and shape. Their corresponding parts, the angles and sides that are in the same positions, are congruent. To identify corresponding parts of congruent triangles, look at the order of the vertices in thethree pairs of congruent angles Examples: Each pair of polygons is congruent. Find the measures of the numbered angles. 3. 4. How can you show that two figures are congruent? Example: Can you conclude that the triangles are congruent. If so, write a congruence statement. 5.

AAS stands for Angle-Angle Side congruence. Two triangles are congruent to each other if any of the two pairs of angles and one pair of corresponding sides are equal to each other. The basis of this theory is the Angle sum property of triangles. According to the angle sum property, the sum of three angles in a triangle is 180°.
