Given: RT 1 SU, RU = RS. Prove: ARUT = ARST Proof: It is given that RT 1 SU. So, because perpendicular lines form Reflexive Property of Congruence. It is given that ARUT = ARST by angles = RT by the = RS. So, and are angles.

**Task: Complete the Paragraph Proof.**

**Given:**  
\( RT \perp SU \), \( RU \cong RS \).

**Prove:**  
\(\triangle RUT \cong \triangle RST\).

**Proof:**

It is given that \( RT \perp SU \). So, \(\angle RUT\) and \(\angle RST\) are right angles because perpendicular lines form right angles. \( \overline{RT} \cong \overline{RT} \) by the Reflexive Property of Congruence. It is given that \( \overline{RU} \cong \overline{RS} \). So, \(\triangle RUT \cong \triangle RST\) by the HL (Hypotenuse-Leg) Congruence Theorem.

**Diagram:**
The diagram shown to the right of the proof is a right triangle configuration with two overlapping triangles, \(\triangle RUT\) and \(\triangle RST\). Line \( RT \) is perpendicular to \( SU \), forming right angles at points \( T \) and \( S \). Both triangles share the hypotenuse \( RT \), and lines \( RU \) and \( RS \) are congruent.

This explanation should help students understand the components needed to complete the proof step-by-step, using specific properties of congruence and right triangles.
