Congruent Polygons and Corresponding Parts
Objective: to name corresponding parts of congruent polygons and write congruence statements for congruent figures.
Vocabulary
Congruent – having the same size and shape
Corresponding – when given congruent polygons, vertices or sides that would line up (match)
Congruent polygons – polygons whose corresponding parts are congruent
Try this:
Fold a piece of paper in half. Without opening the paper, draw a polygon on
one side. Make the polygon be a Scalene ▲. With the paper folded, cut out your polygons
and label all vertices. (use different letters) Place one polygon over the other so that the
sides and angles match. Make a list of the corresponding parts of your
figures. How many corresponding pieces are there? If you were to measure the sides, what
conclusion could you draw?
Can you name the congruent pieces?
Look at page 100.
Looking at the pictures under class exercises can you answer the following questions?
