Congruent Polygons – Have congruent corresponding parts (sides and angles)


Notes
Notes

IMPORTANT: When naming congruent polygons, you must list the vertices in the same order.

ABCD ≅ EFGH


Practice
Practice

  • Name the congruent polygons and find the measures of the numbered angles.


Practice1
Practice

Do 2 and 3 on the 4-1 worksheet.


Naming congruent parts
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




Practice4
Practice

Do 6 and 7 on the 4-1 worksheet.


Deciding if figures are congruent
Deciding if figures are congruent

  • If you can show that all corresponding sides and angles are congruent, then the figures will be congruent.


Important to remember
Important 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.
