CONGRUENCE. {4} A guide for teachers. ASSUMED KNOWLEDGE. • Introductory plane geometry involving points and lines, parallel lines and transversals, angle sums of triangles and quadrilaterals, and general angle?chasing. • Introduction to logical arguments in geometry written as a sequence of steps, each justified by The answer? A triangle congruence theorem like SSS,. SAS, ASA, AAS or HL. This gives us B1: AABCSADEF, by some property, but which one? To find out, start working forward. Listing all of the given information. Prove: AABCSADEF gives us a pair of angles ZA and 2D sandwiched between a pair of congruent sides i w VMDaDdyeR ewGiXtrhu WIknAfBiPndiVt0eM YGgeHoZm0eUt4royA.l. Worksheet by Kuta Software LLC. Kuta Software - Infinite Geometry. Name___________________________________. Period____. Date________________. SSS, SAS, ASA, and AAS Congruence. State if the two triangles are congruent. If they are understand the English expressions for explaining the properties and conditions for congruent triangles (e.g., If two triangles can fit into each other perfectly, they are congruent triangles. When you cut the triangles out and rotate them, they can exactly overlap/coincide with each other. The overlapping sides are called ' Congruent Triangles. Material: page 212 to 220.
