  1. JNV PANCHKULA • TOPIC- TRIANGLE &ITS PROPERTIES • CLASS- VII • SUB.- MATHS • TIME- 40 MIN. • PREPARED BY- MR. KISHAN(TGTMATHS)

  2. TRIANGLES AND TYPES OF TRIANGLES WITH PROPERTIES

  3. We get a TRIANGLE by joining three non collinear points .

  4. What is a TRIANGLE ? • A closed figure formed by joining three line segments is called a TRIANGLE .

  5. A triangle has three sides

  6. A triangle has three angles

  7. TYPES OF TRIANGLES Two Ways • On the basis of angles • On the basis of sides

  8. On the basis of ANGLES Three types • Acute angled triangle • Right angled triangle • Obtuse angled triangle

  9. Acute angled triangle • A triangle whose all the angles are acute is called an ACUTE ANGLED TRIANGLE .

  10. Right angled triangle • A triangle in which one of the angle is right angle is called RIGHT ANGLED TRIANGLE.

  11. Obtused angled triangle • A triangle in which one of the angle is obtuse angle is called OBTUSED ANGLED TRIANGLE .

  12. On the basis of sides Three types • Equilateral triangle • Isosceles triangle • Scalene triangle

  13. Equilateral triangle • A triangle whose all the sides are of equal length is called equilateral triangle.

  14. Isosceles triangle • A triangle whose any two sides are of equal measure is called scalene triangle.

  15. Scalene triangle • A triangle whose no two sides are of equal measure is called scalene triangle.

  16. Recap • A closed figure formed by joining three non collinear points is called • A triangle whose all the sides are of equal length is called • A triangle whose no two sides are of equal length is called • A triangle whose one angle is 90 degree is called • A triangle whose all the angles are less than 90 degree is called
