Question

Please help I don't understand!

Answer 1

AA similarity postulate.

Step-by-step explanation:

Here given that one triangle has 70° and 30°, so other angle should be 80°.

For the other triangle same, it has 30°, 80°, so other angle should be 70°

So when two angles are equal of one triangle to another triangle.

Then the triangles are equal by the AA similarity postulate.
