The construction of copying <QPR is started below. The next step is to set the width of the compass of the length of AB. How does this step ensure that the new angle will be congruent to the original angle?

PA = ST, PB = SU, AB = TU ⇒ ∠P = ∠Q

Step-by-step explanation:

Point S is drawn to mimic point P.

The length of PA is measured and copied to point S so PA = ST.

The length of PB is measured and copied to point U so PB = SU.

Now we know that AB = SU.

Since all of the sides are congruent (if we were to draw a triangle), we can state that the triangles are congruent by Side-Side-Side Congruency Theorem.  Thus, ∠P ≡ ∠S  by CPCTC Theorem.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
