Me understand how to do this!

in δrst shown below, segment su is an altitude:

what property or definition is needed to prove that δrus is similar to δsut?

The correct option is 1.

Step-by-step explanation:

It is given that in ΔRST , segment SU is an altitude. It means the angle SUR and angle SUT are right angles.

It triangle RST and SUT,

        (Definition of altitude)

        (Common angle)

Two corresponding angles are equal. So by AA property of similarity,

             .... (1)

It triangle RST and RUS,

        (Definition of altitude)

        (Common angle)

Two corresponding angles are equal. So by AA property of similarity,

             .... (2)

According to transitive property of equality,

if a=b and b=c, then a=c.

From (1) and (2), we get

            ( Transitive property of equality)

Therefore the correct option is 1.

c
