Do similar angles on a plane make it more stealthy?

I learned in my intro to engineering class at my college that 5th gen fighters (which are stealth aircraft) are designed with similar angles to evade radar. Why is this true? Also, does the angle ...

If all fighter jets become stealthy, how will they fight each other in the future? In dogfights?

I came across this question on dogfight-capable fighter jets still being made. If all aircraft become so stealthy, how will they fight each other? Only in dogfights, I presume. Or am I wrong?

How do friendly stealth planes locate each other?

Stealth planes can't be seen (very well) on radar. So one stealth plane should be unable to locate another stealth plane on its radar and vice versa. So how would one stealth plane locate another, ...

Can doppler radar be used to detect stealth aircraft by focusing on the characteristic flow field instead of the aircraft itself?

Any aircraft traversing through the air would impart velocity, pressure, and temperature gradients to the surrounding air, then there are some phenomenon which are unique to all winged bodies such as ...

How does ATC locate a stealth aircraft if its transponder fails?

Stealth aircraft are built to have near-zero radar visibility, so that, in a warzone, it'll be harder for the enemy to see it on their radars to shoot it down. However, air traffic control also use ...

How does the F-22 Raptor radar reflector work?

The F-22 Raptor (and other stealth aircraft) can be made more visible to radar by using radar reflectors, or in other words, radar cross section (RCS) enhancers. In the comments section of this answer ...
