15. 1.EQUILATERAL TRIANGLE It is a triangle with ALL SIDES EQUAL. This type of triangle is also considered as EQUIANGULAR.

16. 2.ISOSCELES TRIANGLE It is a triangle with TWO SIDES ARE EQUAL.

17. ∠A is called the VERTEX ANGLES ∠B and ∠C are called BASE ANGLES AB = AC

18. 3.SCALENE TRIANGLE It is a triangle with NO EQUAL SIDES .

23. 3. OBTUSE TRIANGLE It is a triangle with a OBTUSE angle.

24. Now, can you tell me all the triangles being mentioned?

25. ACTIVITY TIME! MISSION CONSTRUCTION

26. You will be divided into 4 – 6 groups. You will be given a construction paper, 1/8 illustration board, scissor, glue and a ruler/protractor. Given those materials, you will draw amd create all types of triangles that were discussed lately in a construction paper. Then , cut and paste it on the illustration board. Upon drawing, you will provide a real life example of each type of triangles. (e. g. The roof of the house can illustrate an isosceles triangle). Once the groups are all done, the teacher will call the leader or any representative from each group to present their output in class.
