  1. Congruent triangles class VII Lesson 1 AN INTRODUCTION

  2. MEANING Geometrical figures are said to becongruentif they have same shape and same size

  3. FigureF1 &Figure F2 are congruent covers it exactly ifF1when superposedoverF2 F1 F2

  4. Congruency symbol

  5. FIND THE CONGRUENCY IN THESE RECTANGULAR PLATES

  6. CAN YOU SEE, THE CONGRUENCY IN THESE ARCHES

  7. FIND THE SETS OF CONGRUENT FIGURES HERE

  8. SEE THE CONGRUENT FIGURES

  9. SEE THE CONGRUENT FACES

  10. CONGRUENT SHAPES

  11. CONGRUENT SHAPES

  12. CHOOSE  SHAPES

  13.  SHAPES

  14. congruent figures Squares are congruent if one of their sides equal Circles are congruent if their radii equal Line segments are congruent if their lengths are equal a a

  15. An Angle PENTOGON congruent figures

  16. 12 1 5 13 14 8 3 7 11 16 2 9 10 4 6 15 Choose the congruent figures

  17.   Same shape but not same size

  18. Congruent triangles Two triangles are congruent if three angles and three sides of one triangle are equal to the corresponding three angles and three sides of another triangle

  19. R C A B Q P Corresponding Parts Here  C coincides with  R ,  A with  P &  B with  Q We call the pairs Corresponding parts (angles) Write the other corresponding parts (sides)

  20. Write the corresponding parts DEF MLK ABC  RPQ K P R M L A F D Q C B E

  21. Assignment State true or false 1.When a line segment is bisected we get two congruent line segments 2.When an angle is bisected we obtain two angles which are congruent to each other 3.Circles always have same shape and same size

  22. CONDITIONS FOR CONGRUENCE • SSS • SAS • ASA also AAS • RHS

  23. SSS SAS ASA RHS LET US LEARN ABOUT THIS IN LESSON-2
