Exercise 2 Page 508

Recall that in a rectangle, diagonals bisect each other.

7 58 ft

Practice makes perfect

We are asked to find the measure of SQ using the given information. Let's recall that in a rectangle, diagonals bisect each other.

Since we know that ST=TQ, the measure of TQ is also 3 1316. By the Segment Addition Postulate, we can find the measure of SQ by adding the measures of ST and TQ.

SQ=ST+TQ

SubstituteII

ST= 3 1316, TQ= 3 1316

SQ= 3 1316+ 3 1316
