Triangle SRT is shown. Choose the correct equation or phrase to fill in each blank in
the paragraph.
The vertices of ∆ are S (1, 4) R (2, 2), and T (1, 3). A
reflection across the line (A) [ = 4, = 6, =
− + 5, = − + 6] and then across the line
(B) [ = 6, = 8, = − + 10, = − + 12]
is the same as a translation of 4 units to the right and 4 units
up because the line are ___(C) [congruent, parallel,
perpendicular, similar].

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

f(x)=4
