Not really

for example an eurofighter doesnt look a lot like a gripen or rafale

Lets compare the top view of both the Aircraft now and I will tell you the Actual Reality of the so called copy claim.

(Top view comparison of both the fighter Aircrafts)

( Mirage 2000)

( LCA TEJAS)

Now Front View of Both The Aircrafts—

( Tejas )

(MIRAGE 2000)—

If you look from the front, you will notice that there is a significant amount of difference in both the Planes.

In tejas , the inlets are located just below the wings and in mirage 2000 they are located above the wings, here is another difference.

Side view of both the Aircrafts

( Mirage 2000)

( Tejas )

Now compare the view from the underside of the both Aircrafts , they will look similar but they are not completely the same though right?

( MIRAGE 2000)

( Tejas )

Now compare both the Aircrafts from this angle:

( Tejas )

( Mirage 2000)

Here too you will notice some noticable changes in their respective design. Both Aircrafts have some design similarities in Them ( no doubt about it ) but calling Tejas an outright copy of the Mirage 2000 is absurd in my opinion

So you see they look similar in shape because they both are Delta-wing configuration Fighter Aircrafts in a sense .

So no — Tejas is not an out Right copy of Mirage 2000 fighter aircraft,it is just that both of the Aircraft are Delta wing design so hence they look similar.

Never said that, but the problem imo is that they look a bit too similar though not as much as the J-31 vs F-35. If the IAF had Mirages, it seems pretty likely imo that the guys at HAL did some reverse engineering to accelerate development (although, again, there are the differences and the stuff they themselves developed).

btw In the 1990s,Dassault collaborated with LCA programme. Indian scientists were generally inspired by the delta wing design, as it has a good turn rate, high maneuverability, sustained flight control and is more agile in dogfights. This inspiration became a base for Indian scientists for Tejas to be a delta-wing fighter.

Some more info :
About the delta wing resemblance, Mirage 2000 is based on a pure delta wing design while Tejas has a compound delta wing, which is sometimes referred to as cranked delta due to crank visible from an angle.

Tejas sports an all digital digital Fly-by-wire control system while Mirage 2000 makes use of an Analog Fly-by-wire control system

Mirage 2000 has a cone in it’s inlet ,called the mouse, which is active and regulates air flow into the inlet at different speeds. Hence Mirage 2000 can achieve Mach 2.2 without damaging it’s turbine blades while Tejas doesn’t sport any movable mechanical parts. This restricts it’s top speed to Mach 1.8.But lack of movable parts help in cutting down maintenance time, an advantage for Tejas to act as an interceptor/point defence role.

Tejas has Y-shaped intakes to hide the blades, which help in reducing the frontal RCS of the aircraft. Remarkable fact is RCS of Tejas is 1/6rd of Mirage 2000.

Both are different designs with different avionics. Inspiration is one thing, copying/reverse-engineering is another thing. In development of Tejas, ergonomics was not considered otherwise HAL would have gone for a Mig-21 design, like PAC/CAC developed JF-17,whose origins lie in Mig-21 designs.

lmao yes

If you’re interested in the facts, then have a look at these posts

lol extremely similar

Dasault probably shared the basics of the Mirage to HAL to make the Tejas
