Question

If VX = WZ = 40 cm and m∠ZVX = m∠XWZ = 22°, can ΔVZX and ΔWXZ be proven congruent by SAS? Why or why not?

Answer 1

I believe the answer is C, No, the sides of the triangles intersect.

Answer 2

Answer: The ΔVZX and ΔWXZ are not congruent by SAS.

Step-by-step explanation:

It is given that the VX = WZ = 40 cm and ∠ZVX = ∠XWZ = 22°.

Draw a figure as shown below,

According to the SAS rule of congruence, two triangles are congruent if two sides and their inclined angle is equal.

From the given figure it is easily noticed that in ΔVZX and ΔWXZ,

`VX=WZ=40cm` (given)

`\angle ZVX=\angle XWZ=22^(\circ)` (given)

`XZ=XZ` (common side)

Since we have two sides and one angle is same. but we can not conclude that the ΔVZX and ΔWXZ are congruent by SAS, because the given angle is not the inclined angle of both equal sides.

Therefore, the ΔVZX and ΔWXZ are not congruent by SAS.
