This looks like were trying to prove a pair of angles of an isosceles triangle are congruent.
To do that we need the fact that it's an isosceles triangle, which is AB=AC.
That's choice A.
None of the other choices make sense just by symmetry. AD=AC, nope the middle and the side, BD=AD, nope, AB=BD, nope.
choice A.
For this case, we have that by definition:
<em>The supplementary angles are those that in pair add up to 180 degrees.
</em>
On the other hand, a linear pair is a pair of adjacent angles formed when two lines intersect each other.
By definition, <em>the two angles of a linear pair are always supplementary, this means that their measurements add up to 180 degrees.
</em>
Answer:
The two angles of a linear pair are always supplementary
Answer: 90 degrees
Step-by-step explanation:
Same-side interior angles thm states that the 90 deg angle and angle 3 are supplementary.
