Question

FInd each error and make the corrections

Answer 1

Answer:

Exercise 1

1) Δ ABC ≅ Δ EDC

From the figure:

a) $m\angle ABC\cong m\angle EDC$    [Given]

b) $BC=DC$                                              [Given]

c) $m\angle BCA\cong m\angle DCE$    [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) $m\angle WXY\cong m\angle ACB$    [Given]

b) $XY=CB$                                              [Given]

c) $m\angle XYW\cong m\angle ABC$    [Given]

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

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