2.THREE SIDES
3.THREE ANGLE –ALL ANGLES
MEASURMENT IS 180°

5. DEFINITION:
The geometrical figure having
three vertices, three sides and
three angles and all angles
measurement is 180° that is
called TRIANGLE.

6. TRIANGLE: IN TRIANGLE ABC,
VERTICES means where the
A
two sides are joined, that
point is called vertices.
Here Point A,B,C are
VERTICES.
SIDE means in between two
point the segment is called
SIDE. Here sides are side
B C
AB ,side BC , side AC.
ANGLE means where the two
sides joined and forms

7. TYPES OF TRIANGLE BY
ANGLE
ACUTE ANGLE
TRIANGLE
RIGHT ANGLE
TRIANGLE
OBTUSE ANGLE
TRIANGLE

8. ACUTE ANGLE TRIANGLE
In the triangle all angles are acute
are called ACUTE ANGLE
TRIANGLE
Acute means less than 90°

9. RIGHT ANGLE TRIANGLE
In triangle, one angle is right angle is
called RIGHT ANGLE TRIANGLE.
Right angle means 90°.
The sign of 90° is ┘

10. OBTUSE ANGLE TRIANGLE:
In triangle, where one angle is obtuse
is called OBTUSE ANGLE
TRIANGLE.
An obtuse angle means a angle more
