The number of permutation that can be formed with the letters of the word TRIANGLE is

Write each of the following sentences in symbolic form using statement variables p and q. (i) 19 is not a prime number and all the angles of a triangle are equal. (ii) 19 is a prime number or all the angles of a triangle are not equal. (iii) 19 is a prime number and all the angles of a triangle are equal. (iv) 19 is not a prime number.

If two angles of one triangle are respectively equal to two angles of another triangle; then two triangles are similar.

A triangle in which all the sides / angles are equal is called __ triangle.
