Question

Given:

Answer 1

The symmetric property and perpendicular property

Answer 2

Answer:

the only following lines which support the conclusion based on the given information is, RZ = RZ , Reflexive Property

Explanation:

HL (Hypotenuse Leg) theorem states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

In ΔRZS and ΔRZT

$\angle 3 = \angle 4 = 90^{\circ}$   [Given]

RS = RT             [Hypotenuse side]        [Given]

RZ = RZ            [Reflexive property]      

Then, by the HL theorem;

$\triangle RZS \cong \triangle RZT$               Hence proved!
