Question

Which angel do ΔEBC and ΔADC share?

a. Less than EFD
b. Less than ECA
c. Less than CAF
d. Less than ADC

Answer 1

The triangles ΔEBC and ΔADC share the angle ECA

Step-by-step explanation:

The two triangles ΔEBC and ΔADC share the angle ECA.

1. First, we identify the common vertex between the two triangles, which is vertex C.
2. Then, we can see that both ΔEBC and ΔADC have side AC in common.
3. The angle formed by the sides AC and BC in ΔEBC is angle ECA, and the angle formed by the sides AC and DC in ΔADC is also angle ECA.

Therefore, we can conclude that ΔEBC and ΔADC share the angle ECA.
