Pq and rs are two lines that intersect at point t, as shown below: two lines pq and rs intersect at point t. angles ptr and stq are shown congruent. which fact is used to prove that angle ptr is always equal to angle stq? if two angles are equal to the same measure, then the angles are congruent. if two angles are equal to the same measure, then the angles are supplementary. lines pq and rs have a fixed length. lines pq and rs intersect at right angles.

Answer with explanation:

It is given that , two lines, P Q and RS intersect at point T.

Also, it is given that⇒∠P TR≅ ∠S T Q

To prove this fact, we will use the following statement

Option A⇒If two angles are equal to the same measure, then the angles are congruent.

answer: options?

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
