What data must be added so that the triangles are congruent?
What data must be added so that the triangles are congruent?
Let's consider that:
DF = AC = 8
DE = AB = 5
8 is greater than 5, therefore the angle DEF is opposite the larger side and is equal to 65 degrees.
That is, the figure we are missing is the angle of the second triangle.
We will examine which angle is opposite the large side AC.
ABC is the angle opposite the larger side AC so it must be equal to 65 degrees.
Angle ABC equals 65.
