45-45-90 Right Triangle Example with Hypotenuse 2√2 #1494768 (License: Personal Use)

This hand-drawn diagram shows triangle DEF, a classic 45-45-90 right triangle with the right angle at vertex E. The hypotenuse DF is labeled 2√2, implying each leg (DE and EF) measures 2 units, following the √2 : 1 : 1 ratio. The clean labeling and angle notation make it ideal for geometry instruction or trigonometry reference.

Used in educational math content-especially geometry lessons on special right triangles-to demonstrate side-length relationships, Pythagorean theorem verification, and trigonometric ratios. Matches user intent for visual learning, homework help, or exam prep.
