  4. Participants • Abhirami A J • Sherin Beegam • Devika S School : Govt G H S S COTTONHILL

  5. Introduction We have studied the properties of triangles & construction of triangles when the three sides are given. from the properties of triangle they can be classified as, • Right angled triangle • Equilateral triangle • Isosceles triangle The sum of the internal angles of a triangle is 180 degrees. For forming a triangle, the sum of the two smaller sides has to be more than the longer side. In this project, we are studying the properties of an isosceles triangle.

  6. Aim The aim of this project is to study the properties & construction of an isosceles triangle.

  7. Methodology • The method of constructing an isosceles triangle is taken from the text book &with the help of teachers

  8. Properties of an isosceles triangle • When two sides of a triangle are equal, it is called an isosceles triangle. • When two sides of a triangle are equal invariably, the two adjacent angles have to be equal.

  9. Points to be remembered • For constructing the isosceles triangle, the length of the equal side & the other length has to be known. • Otherwise, the length of the non equal side & an angle has to be known. • We can represent Isosceles Triangle ABC as ABC

  10. How to draw an isosceles triangle • When the sides are given. • For example, Construct a triangle with base of 8 cm & equal sides of 5 cm As the sum of the small sides comes to 10 cm, which is greater than 8 cm; it is possible to draw a triangle

  11. Step 1 • Draw a base line of length 8 cm & name left end as A and right end as B

  12. Step 2 • Take 5 cm length in a compass and draw an arc placing the pointer at A.

  13. Step 3 • Now, place the pointer on B and draw an arc to cross the previous arc. This intersection point is named as C. C

  14. Step 4 • Now, join the intersection of the arcs C with A & also with B.The triangle will be formed as below. C

  15. ISOSCELES TRIANGLE ABC C

  16. Conclusion • By analyzing this project & activities we have done, we can conclude that construction of an isosceles triangle is not complicated. And it is very interesting

  17. Thanks We thank our respected I.T teacher who gave instructions & encouraged us to do this project. We thank each & every one who helped to do this activity Thanks.......
