Special Right Triangles
Special right triangles are right triangles with specific angle measures that result in unique properties and relationships between their sides. The two most common types of special right triangles are 45-45-90 triangles and 30-60-90 triangles.
45-45-90 Triangles
- All angles measure 45°, 45°, and 90°.
- The ratio of the sides is 1:1:√2.
- The hypotenuse is √2 times longer than each leg.
- The area is given by A = (1/2)s², where s is the length of a leg.
30-60-90 Triangles
- All angles measure 30°, 60°, and 90°.
- The ratio of the sides is 1:√3:2.
- The hypotenuse is 2 times longer than the shorter leg.
- The area is given by A = (1/4)s², where s is the length of the shorter leg.
