Look at the figure. Name the postulate or theorem you can use to prove the train goes congruent?
Nikolay [14]

Let us recall parallelogram properties, which states that opposite angles of parallelogram are congruent.

We can see from graph that side US is parallel to TR and measure of angle U equals to measure of angle R, therefore, quadrilateral drawn in our given graph is a parallelogram.

Since we know that opposite sides of parallelogram are congruent. In our parallelogram UT=SR and US=TR.

In our triangle STU and triangle TSR side TS=TS by reflexive property of congruence.

Therefore, our triangles are congruent by SSS congruence.

I need help fast please...
BARSIC [14]

Answer:

87: y = 5

88: y = 0

89: y = -2

90: y = -1/2x + 9

91: y = 2x - 16

92: y = x - 11


Step-by-step explanation:

To find the slope(m): (y1 - y2)/(x1 - x2)

To find the y-intercept:

y = mx + b

Replace m with the slope and x and y with one of the sets of coordinates. Then simplify to get the y-intercept. Use the equation y = mx + b and replace m with the slope and b with the y-intercept to get the equation.


(Sorry if this is a little confusing.)
