What postulate or theorem can be used to prove that these two triangles are congruent? PLEASE HELP I REALLY NEED IT!!!
I will give brainliest.
Use the picture

Step-by-step explanation:

The attached figure shows two triangles AOB and MON.

In triangles AOB and MON,

AB = MN (Given )

∠AOB = ∠MON (vertically opposite angles)

∠O = ∠O (common)

∴ ΔAOB ≅ Δ MON (ASA)

Angle-side-angle is the postulate that can be used to prove that two triangles are congruent.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
