The construction of copying ∠"QPR" is started below. The next step is to set the width of the compass to the length of ("AB" ).

Answer:

The length AB equals length TU.

Step-by-step explanation:

Procedure: Replicate angle <QPR so that;

<QPR matches <TSU

Set the compass so that each leg touches points A and B to replicate the distance AB.

Next, position the compass at T to draw an arc that marks point U. Draw a straight line from S to U.

Consequently,

<QPR is congruent to <TSU

This method guarantees that angles are congruent by maintaining the same radius, thus AB = TU.
