RGeom4.3and4.4.notebook November 09, 2016 Warm-Up Write a congruency statement for triangle CAT and triangle DOG. G A C T D O Remember .... To prove figures are congruent, all sides and all angles must be congruent for triangles, that means 6 things congruent - 3 angles and 3 sides 1 RGeom4.3and4.4.notebook November 09, 2016 Review: Hypotenuse of a Triangle (the side of the triangle ACROSS from the right angle) (also .... the longest side in a right triangle) 2 RGeom4.3and4.4.notebook November 09, 2016 Included Sides and Angles: Included Angle Which angle is the included angle for sides XZ and YX?? (the angle between two given sides) X Y Z Included Side (the side between two given angles) Which side is the included side for angles CBA and CAB?? B A C 3 RGeom4.3and4.4.notebook November 09, 2016 Triangle Congruence Theorems If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. 4 RGeom4.3and4.4.notebook November 09, 2016 Triangle Congruence Theorems If two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the two triangles are congruent. 5 RGeom4.3and4.4.notebook November 09, 2016 Triangle Congruence Theorems If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the two triangles are congruent. 6 RGeom4.3and4.4.notebook November 09, 2016 Notes Packet - pg. 10 Decide whether the congruence is true. Explain your reasoning. 7 RGeom4.3and4.4.notebook November 09, 2016 Pick the congruent triangles (if there are any) and write a congruency statement. Remember, in Congruence statements ________________ matters!! 8 RGeom4.3and4.4.notebook November 09, 2016 9 RGeom4.3and4.4.notebook November 09, 2016 10
