If quadrilateral PQRS is a rectangle, then which of the following is true?
brilliants [131]

∠STP ≅ ∠QTR is the True statement ⇒ answer C

Step-by-step explanation:

In any rectangle

1. Each two opposite sides are equal and parallel

2. The measure of its vertex angles is 90°

3. The two diagonals are equal

Now lets find the true statements

∵ PQRS is a rectangle

∴ PS = QR ⇒ opposite sides

∴ PQ = SR ⇒ opposite sides

∴ PR = QS ⇒ diagonals

A.  ∠PSQ ≅ ∠QSR

∵ The diagonals of the rectangle do not bisect the vertex angles

∴ AQ does not bisect angle S

∴  m∠PSQ ≠ m∠QSR

∴  ∠PSQ not congruent ∠QSR

∠PSQ ≅ ∠QSR ⇒ False

B. segment SR ≅ segment RQ

∵ SR and RQ are two adjacent sides

∵ The adjacent side in the rectangle not equal

∴ SR ≠ QR

∴ segment SR not congruent to segment RQ

segment SR ≅ segment RQ ⇒ False

C. ∠STP ≅ ∠QTR

∵ PR intersects QS at point T

∴ m∠STP = m∠QTR ⇒ vertically opposite angles

∴ ∠STP ≅ ∠QTR

∠STP ≅ ∠QTR ⇒ True

D. segment PS ≅ segment PR

∵ PS is a side in the rectangle

∵ PR is a diagonal in the rectangle

∵ The side of the rectangle not equal the diagonal of the rectangle

∴ PS ≠ PR

∴ segment PS not congruent to segment PR

segment PS ≅ segment PR ⇒ False

∠STP ≅ ∠QTR is the True statement

What is the y-intercept of y=[x-41 +1?<br> ○ (0,-5)<br> O (5,5)<br> (0,5)<br> ○ (5,0)
Dmitriy789 [7]

The y-intercept of the given function is (0, -5)

<h3>y-intercept of an equation</h3>

Given the equation below

y=[x-4| +1

The y-intercept is the point where the value of x is zero. Substitute x = 0 into the function to have;

y = 0 - 4-  1

y = 0 - 5

y = -5

Hence the y-intercept of the given function is (0, -5)

1. Suppose D has a coordinate of 11 and DE = 5. What are the possible<br> midpoints of DE?
Rasek [7]

Answer:

The possible midpoints are (5.5,8) and (5.5,3)

Step-by-step explanation:

Given

D = 11

DE = 5

Required

Determine the midpoint of DE

First, we need to determine the coordinates of E

If E is to the right of DE;

E - D = 5

E - 11 = 5

E = 11 + 5

E = 16

Hence, the coordinate is (11,16)

Midpoint = \frac{1}{2} * (11,16)

Midpoint =  (5.5,8)

Else:

D - E = 5

11 - E = 5

E = 11 - 5

E = 6

Hence, the coordinate is (11,6)

Midpoint = \frac{1}{2} * (11,6)

Midpoint = (5.5,3)

<em>The possible midpoints are (5.5,8) and (5.5,3)</em>
