Find each error and make the corrections

Exercise 1

1) Δ ABC ≅ Δ EDC

From the figure:

a)    [Given]

b)                                              [Given]

c)    [Vertical angles are congruent]

∴ Δ ABC ≅ Δ EDC                                                [A.S.A postulate]

2) The triangles are congruent by A.S.A postulate.

Exercise 2

1) Δ WXY ≅ Δ ACB

From the figure:

a)    [Given]

b)                                              [Given]

c)    [Given]

∴ Δ WXY ≅ Δ ACB                                                [A.S.A postulate]

2) The triangles are congruent by A.S.A postulate.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
