This helpful geometry diagram shows the parts of a right triangle: the adjacent, the opposite, and the…wait. What? (A classic Boynton design from 1980, which she redrew in 2013.)

Of course, Sandra Boynton pictures are always fun. Looking forward to sending some “happy mail” to my math teacher friend. This card is printed well, good colors & spacing.

Exactly what I wanted, it is very difficult to acquire Vintage Australiana items. I am so please that I ordered 8 I will be using them for my scrap booking and Junk Journaling. Gorgeous, Zazzle produced and delivered exactly what I wanted.

Way better quality than I ever expected. I love the colours, font and quality of the card. I'm so pleased I found Zazzle as it is near impossible to purchase Vintage or Retro Australian memorabilia online. I chose this design when I purchased them. They are perfect for my projects. I was very specific about what I wanted. I know where to come now when I need to order similar items.
