  2. Homework Check

  3. Today’s Objectives • Students will review the definition of congruency. • Students will be able to write congruence statements given two congruent triangles. • Students will be able to identify corresponding congruent parts given a congruence statement.

  4. Review • Two figures are CONGRUENT if they have…. • SAME SIZE • SAME SHAPE How is this different than similar?

  5. Name 6 congruent parts. B E A F C D

  6. Turn to Page 30 in your book • Complete ALL of page 30 and the • first half of page 31 ( stop at Example)

  7. Congruence Statements • Saying ABC is congruent to FED is not the same as saying ABC is congruent to DEF. • To properly write a congruence statement, the congruent angles must fall at corresponding spots.

  8. Let’s Pratice- turn to page 33

  9. Let’s Pratice- turn to page 33

  10. Name ALL congruent angles and sides

  11. If m<B=40 and m<O = 25, Find the measures of all other angles.

  12. If BG=2x+5 and FX=3x-8. Find x.

  13. Homework • Kuta Software- Congruence and Triangles • Page 34 and 35
