Question

show how √5 can be represented on the number line
​

Answer 1

Resposta:

Take a line segment AB = 2 units (consider 1 unit = 2 cm) on x-axis. Draw a perpendicular on B and construct a line BC = 1 unit length. Join AC which will be √5 (Pythagoras theorem). Take A as center, and AC as radius draw an which cuts the x-axis at point E
