PLZ HELP here are three triangles shown separately, these triangles are similar. How do you know?

Using the AA similarity postulate, you can determine that these triangles are similar.

Step-by-step explanation:

All three triangles are right triangles, so they all have 90° angles.

Angle B is present in the large and small triangle. Therefore, you know those 2 triangles are similar. You can also prove that angles A and C are the same.

A and B are complementary angles in the large triangle and the same with B and C in the small one. Since B ≅ B by Reflexive Property, A and C must have the same angle measurement since they are complements of the same angle.

the answer would be c:   ax + b = ax + c

step-by-step explanation:

i hope this is what you were looking for.
