Aim: How are triangles congruent? Do Now: Solve each proportion. 4 = 7 2. 2.8 = 4.2 16 x h 12

Vocabulary Congruent polygons – polygons that have the same shape and size Angles measure the same (look for angle notation) The length of the sides are the same (look for tick marks) SYMBOL   Order matters!! Corresponding Parts – parts of the congruent triangles that “match”

Example Determine the corresponding parts.
