**Warmup**• Complete the Statement: • When parallel lines are cut by a transversal, • Alternate Interior Angles are ___________ • Same Side Interior Angles are__________ • Corresponding Angles are__________**Learning Target**• I can identify the corresponding parts of congruent figures**Congruent Polygons – Have congruent corresponding parts**(sides and angles) • IMPORTANT: When naming congruent polygons, you must list the vertices in the same order. • EXAMPLE**Name the congruent polygons and find the measures of the**numbered angles.**Name the congruent polygons and find the measures of the**numbered angles. • Do number 2 and number 3 on the worksheet.**Naming Congruent Parts**• You need to be able to name congruent corresponding parts of congruent polygons…so you need to pay attention to the vertices in the name of the polygon**Deciding if figures are congruent**• If you can show that all corresponding sides and angles are congruent, then the figures will be congruent. • Important things to remember. • Vertical Angles are congruent. • If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent.**Is triangle GHJ congruent to triangle IHJ?? Be able to**explain why.**RECAP**• Naming Congruent Polygons (#1-3) • Find missing values of congruent polygons.(#1-3) • Name corresponding parts of congruent polygons.(#4-7) • State whether 2 figures are congruent or not(#8-9) • Provide reasons in proofs**HMWK**• P. 182-183 #3-11 odd, 14-27 all
