Construction Of A Triangle

TRIANGLE • A triangle is one of the basic shapes of geometry: a polygon with three vertices and three sides which are straight line segments.

PARTS OF TRIANGLE A TRIANGLE HAS SIX PARTSq. THERE ARE THREE SIDES AND THREE ANGLES. TRIANGLES SIDES AB=4CM BC=4.5CM AC=5CM TRIANGLES ANGLE A=60

B=50

C=70

TYPES OF TRIANGLES ON THE BASIS OF SIDES SCALENE TRIANGLE ISOSCELES TRIANGLE EQUILATERAL TRIANGLE

SCALENE TRIANGLE A TRINGLE HAVING ALL DIFFERENT SIDES IS CALLED SCALENE TRIANGLE.

ISOSCELES TRIANGLE A TRIANGLE WHOSE TWO SIDES ARE EQUAL, IS CALLED AN ISOSCELES TRIANGLE

EQUILATERAL TRIANGLE • A TRIANGLE WHOSE ALL SIDES ARE EQUAL TO ONE ANOTHER, IS CALLED AN EQUILATERAL TRIANGLE

TYPES OF TRIANGLE ON THE BASIS OF ANGLES

ACUTE TRIANGLE RIGHT TRIANGLE OBTUSE TRIANGLE

ACUTE TRIANGLE A TRIANGLE WHOSE ALL THE ANGLES ARE ACUTE, IS CALLED AN ACUTE TRIANGLE

RIGHT TRIANGLE A TRIANGLE HAVING ONE ANGLE 90, IS A RIGHT ANGLED TRIANGLE

OBTUSE TRIANGLE A TRIANGLE WHOSE ONE ANGLE IS OBTUSE,IS CALLED AN OBTUSE TRIANGLE

SUM OF THE ANGLE OF ATRIANGLE IS 180
