By giving a counter-example, show that the following statement is false:
p: If all the sides of a triangle are equal, then the triangle is obtuse angled.

By giving a counter example,show that the following statement is not true: p: if all the angles of a triangle are equal,then the triangle is an obtuse angled triangle.

By giving a counter example,show that the following statements are not true.(i) p: If all the angles of a triangle are equal,then the triangle is an obtuse angled triangle.(ii) q: The equation x^(2)-1=0 does not have a root lying between 0 and 2.

By giving a counter example,show that the following statement is false.If n is an odd integer,then n is prime.

By giving a counter example, show that the following statement is false. "If n is an odd positive integer, then n is prime."

The lengths of the sides of a triangle are 3, 5 and 7. Show that the triangle is obtuse-angled.

Angles opposite to two equal sides of a triangle are equal.

By giving a counter example , show that the following statements are false (i) If sqrtp is an irrational number then p is prime number (ii) Square of every rational number is greater than the number itself (iii) If all the angles of a quadrilateral is equal then it is regular

If 6,10,14 are the sides of a triangle then it's obtuse angle is

Let a<=b<=c be the lengths of the sides of a triangle.If a^(2)+b^(2)
