SAS

Step-by-step explanation:

TWO SIDES ARE GIVEN EQUAL

angleACB=angleDCE ( vertically opposite angles )

so done it's SAS

SAS

Step-by-step explanation:

We can see already that

AB = ED

BC = DC

So it must have 2 S's.

Then we can see ∠ACB = ∠ECD because of verticals.

This gives us the SAS rule.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
