Betelgeuse is much larger than Rigel. Betelgeuse has a radius about 15 times the radius of Rigel, and a volume of about 3500 times Rigel.
Rigel is a blue-white star, while Betelgeuse is a red supergiant star.
Rigel is brighter than Betelgeuse. Rigel is a blue supergiant star and one of the brightest stars in the night sky, while Betelgeuse is a red supergiant and although it is one of the largest stars known, it is not as bright as Rigel.
Betelgeuse is larger than Rigel. Betelgeuse is a red supergiant star with a diameter about 1,180 times that of the Sun, while Rigel is a blue supergiant with a diameter roughly 79 times that of the Sun.
Rigel is brighter than Betelgeuse. Rigel is a blue supergiant star that is one of the brightest stars in the night sky, while Betelgeuse is a red supergiant star that is dimmer in comparison.
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.

Betelgeuse and Rigel are stars in the constellation Orion. Betelgeuse is a red supergiant and Rigel is a blue-white supergiant, and both are easily visible to the naked eye in the Orion constellation.
No, Rigel is hotter than Betelgeuse. Rigel is a blue supergiant star with a surface temperature of around 12,000 Kelvin, while Betelgeuse is a red supergiant with a surface temperature of around 3,500 Kelvin.
Quite simply because Rigel is still on the main sequence whereas Betelgeuse has come off the main sequence and is only fusing helium in it's core, whereas Rigel is still fusing hydrogen in it's core. This is the reason for the difference in temperature.
Betelgeuse is around 10 times greater in diameter than Rigel.
Both Betelgeuse and Rigel are listed as being only 10 million yeas old, compared to the sun's 4.5 billion. Both are also expected to supernova soon, though Betelgeuse is expected to go out sooner, as it's been anticipated since 2011.
Betelgeuse is a red supergiant star and the Rigel is a blue supergiant. Both are in the same constellation Orion
Betelgeuse, a red supergiant star, has an effective surface temperature of around 3,500 Kelvin, while Rigel, a blue supergiant, has a much higher surface temperature of about 11,000 Kelvin. This significant difference in temperature is due to their stages in stellar evolution and their respective spectral classifications, with Betelgeuse being cooler and redder, and Rigel being hotter and bluer. Consequently, Rigel emits more energy than Betelgeuse, influencing their brightness and appearance in the night sky.
