The full height of the blue triangle (sin(a)) can’t be used, since the red triangle doesn’t extend as far. (Why? When we add angle b, we’re moving at a steeper angle with the same hypotenuse. We gained vertical distance and lost horizontal distance.) We’re effectively “sli...
The observed BaM reflections are shown by triangle symbols at the Bragg angles according to the PDF-2 card 01-075-9113. The space group of the BaM phase is indicated in the figure. XRD patterns contain reflections of the α-Al2O3 phase (space group 𝑅3̲𝑐R3¯c (167) in a...

Triangles are one of the most fundamental shapes in geometry. A triangle is a polygon with three sides and three angles. The sum of the interior angles of a triangle is always 180 degrees. There are different types of triangles based on their sides and angles. Triangles can be classified as...
