Sum Of Lenghts Of Two Sides Of A Triangle (Ex-6.4)

The sum of the lengths of the sides of a triangle is called its .............

Perimeter of a triangle the sum of the lengths of the sides of a triangle is called its perimeter.

Find the set of all real 'a' such that 5a^(2)-3a-2,a^(2)+a-2 and 2a^(2)+a-1 are the lenghts of the sides of a triangle?

Each of sides of a triangle is 8cm less than the sum of its other two sides.Area of the triangle ( in cm^(2)) is

If length of two sides of a triangle are 6 cm and 10 cm, then the length of the third side can be

Fill in the blanks with lt or gt (a) (Sum of any two sides of a triangle)….. (the third side). (b) (Difference of any two sides of a triangle)….(the third side). (c) (Sum of three altitudes of a triangle)….(sum of its three sides). (d) (Sum of any two sides of a triangle)…..(twice the median to the 3rd side). (e) (Perimeter of a triangle)....(sum of its three medians).

If midpoints of the sides of a triangle are (0, 4), (6, 4) and (6, 0), then find the vertices of triangle, centroid and circumcentre of triangle.

Sum of any two sides of a triangle is greater than the third side.
