Answer:

Yes

Step-by-step explanation:

All the sides must add up to 180 degrees. So, you already know that one triangle is 40 degrees and 60 degrees. So, 40 + 60 = 120 ✔. 180 – 120 = 80. The other triangle is 80 degrees and 40 degrees. 80 + 40 = 120 ✔. 180 – 120 = 80. To check your work, 40 + 60 + 80 = 180 degrees ✔ So, yes, these two triangles are equal (similar) to each other.
