If the measure of three angles of a triangle are in the ratio 2 : 3 : 5, then the triangle is :
Let the angles of the triangle be $$2x, 3x$$ and $$5x$$
According to angle sum property :
=> $$2x + 3x + 5x = 180$$°
=> $$x = \frac{180}{10} = 18$$°
$$\therefore$$ the angles are 36°, 54° and 90°
=> It is right angled triangle.
