Question

Can a triangle have 72° as its vertex angles? Explain

Answer 1

Answer:

A triangle cannot have 72°, 100°, 30° because the sum of all angles of a triangle is always equal to 180°. Since, the sum of 72°, 100° & 30° = 202° is not equal to 180°. HENCE, 72°, 180° & 30° cannot be vertex angles of a triangle.
