POWER POINT PRESENTATION ON TRIANGLE AND ITS PROPERTIES : POWER POINT PRESENTATION ON TRIANGLE AND ITS PROPERTIES
Defination of Triangle : Defination of Triangle A triangle is a simple closed curve made of three line segment. A c B It has three vertices-A,B,C
Three sides - AB,BC,CA
Three angles-<A,<B,<C
Slide 3: Classification Of Triangles Classifying Triangles by Sides:- Scalene triangle:- A triangle having all the sides are unequal are called scalene triangle. c A B 5cm 8cm 4cm
Slide 4: Isosceles triangle:-a triangle having two sides are equal are called isosceles triangle. A B c 5cm 5cm 8cm
Slide 5: Equilateral triangle:-A triangle having all sides are equal are called equilateral triangle. 6cm 6cm 6cm A B c
Slide 6: Classifying Triangles by angles- Acute-angles triangle:-A triangle having all the angles are greater than 0 but less than 90 are called Acute-angles triangle. o o A B c o 70 o 60 o
Slide 7: Right-angled triangle:-A triangle having one angle is 90 is called Right-angled triangle. o 90 o B A c
Slide 8: Obtuse –angled triangle:-A triangle having one angle is greater then 90 but less than 180 is called Obtuse –angled triangle. o o 120 o B A c
Slide 9: Medians of Triangle Median of the triangle:-A line segment joining the vertex of a triangle to the mid point of its opposite side is called a median of a triangle. D c B A AD= median
Slide 10: Altitudes of Triangle Altitudes of triangle:-The perpendicular line segment from a vertex of a triangle to its opposite side is called an altitude of a triangle. D A B c
Slide 11: Exterior Angle of a Triangle Exterior angle of a triangle:-An exterior angle of a triangle is formed when a side of a triangle is produced. At each vertex, you have two ways of forming an exterior angle. A B c D <ACD=Exterior Angle.
Slide 12: Interior Angle of a Triangle Interior angle of a triangle:-An interior Angle of a triangle is formed inside of a triangle. B c A <A<B<C=Interior Angle.
Slide 13: Base Perpendicular Hypotenuse A B C Pythagoras Theorem ( AC) 2 = (AB) 2 + (BC) 2
Hypotenuse 2 = Perpendicular 2 + Base 2 In a right triangle, the square of the longest
side is equal to the sum of squares of remaining two sides.
