The half square triangle unit is probably the most commonly used patch in a quilt block -- well it is second only to the square. It is made simply with two triangles, filling up half the square each -- hence the name. Take a quick look through this website, or in any quilting magazine, and you will start to notice that this half square triangle, regardless of its size, is present in more quilts than not.

Zenith was fun to create and I did take a few liberties with its construction. Those rectangles were supposed to be two squares sewn together, but my theory is why make a seam when it is unnecessary? I also changed up some of the colour placements, but then, I'm allowed, since it is my block!
Half square triangles are plentiful and this block also includes my favourite patch -- the flying geese unit. Oops, I almost forgot to mention the centre patch is made using the square in the square patch. I also included this block in the pinwheels category because, depending on the block layout, they may emerge as a secondary pattern, which is always fun.
There is nothing difficult in constructing this quilt block and you can make some really interesting quilts by adding sashing and/or setting the blocks on point. The discovery is awaiting you.
