2. Name of the student Teacher : VEENA VALSAN Subject: Mathematics Unit : Similar triangles Subunit : Similar triangles Name of the school : Standard : IX Strength : Date : Time : Curricular Statement : Understanding the peculiarity of similar triangles CONTENT ANALYSIS Term : Similar triangles Fact : Angles of similar triangles are equal Concept : The sides opposite to the equal angles are in proportions

3. Learning outcomes T he pupil will be able to, 1.Retriving the concept of similar triangles 2.Highlighting the concept of similar triangle 3.Searching the beauty of geometric figures 4.Using the idea in the familiar situation 5.Comparing the different similar triangles Pre-Requisite s : students knows the concept of triangles and other side and angles Teaching learning resource : Activity card, usual classroom aid

4. Class room interaction procedure Expected pupil response INTRODUCTION Teacher start with the class by a new method. Teacher sings a poem. Geometrical shapes We are in different shapes We are in different angles We are in three sided We are in 4 sided and more We have sides We have angles Then tell what is our name? PRESENTATION Teacher divided the class to 4 groups and give them activity cards. In the activity cards ,it contain a riddle. Teacher ask the students to answer the riddle.

5. “I am a geometrical figure I have sides and angles The number of sides and angles are equal to the number of wheels of auto rickshaw. My sides can be changed but Sum of my angles are always 180 ⁰ Can you tell my name” Triangles Activity -1 Teacher again give activity card to the students and ask them to answer it. Name the triangle and complete the table below Triangles Angles

6. Students do it by the discussion, and explanation. Teacher also help the students to found out that the triangle with equal angle are equal Activity – 2 Teacher again give activity cards to the students. Draw triangles with angles 40 ⁰,60⁰ and 80⁰ ? 2. Name the triangle ? 3.Measure the angles of the triangle ?

7. Students do the discussion and explanation with the help of the teacher, students found out that if the angles of a triangles are equal to the angles of another triangle then the two triangles are similar and the sides opposite to the equal angles are in proportion. Teacher then show a chart. Similar Triangles If the angles of a triangle are equal to the angles of another triangle, then the two triangles are equal and the sides opposite to the equal angles are in proportion . Teacher then sing a poem

8. At last he comes near to me We are of equal mind But are of different sides As our mind our angles are equal Our fathers call us . Similar Triangles

9. Review Giving cards to the students and ask to find the answer

10. Follow –up activity 1.Make similar triangles using eerrkkiles 2. Draw similar triangles using angle as 45 ⁰,30⁰ and 105⁰
