Triangle Memes

The classic triangle on a flat plane: "Yes, angles add up to 180°." But then non-Euclidean geometry crashes the party with a spherical triangle where angles sum to >180°! This is the mathematical equivalent of thinking you've mastered the game until someone changes the playing field. Euclidean geometry is like that friend who follows all the rules, while non-Euclidean geometry is the chaotic genius who says "rules are more like... guidelines." Next time someone confidently states a mathematical "fact," just whisper "but on a sphere though..." and watch their existential crisis unfold.

Your friend isn't stupid, just mathematically transcendent. This right triangle contains the golden ratio (φ ≈ 1.618...) hidden in plain sight. The hypotenuse (3.80422...) divided by the base (2) equals 1.902... which is... completely meaningless. The angle is 58.28°, also irrelevant. And that 1+√5 expression? That's actually the formula for φ, but it equals 3.236... not whatever they're claiming here. So yes, your friend is absolutely wrong. This is just a random triangle with arbitrary numbers slapped on it by someone who failed both geometry and Greek mythology. The only "golden" thing here is the comedy.

The real question isn't finding the perimeter—it's finding whether this triangle can even exist ! With sides (3a+7), (a-14), and (2a-1), you'd need to satisfy the triangle inequality theorem: the sum of any two sides must exceed the third side. For most values of 'a', that (a-14) side is going negative faster than my motivation during finals week. The student's answer "6a-8" is technically correct for the perimeter, but they skipped the existential crisis of whether this shape is even possible in our reality. Math teachers love throwing these geometric paradoxes at us just to watch our souls leave our bodies.

Geometry teachers having a collective meltdown right now! This "triangle" is actually a hexagon with completely impossible angle measurements that add up to 720° instead of the required 180° for a triangle. It's like someone took a geometry textbook, threw it in a blender, and served it with a straight face. Even Euclid is rolling in his grave so fast he could power a small city. This is what happens when you skip math class to watch TikTok tutorials on "alternative geometry."

The green rage monster is weeping because he can't remember the formula for a triangle's perimeter—which is hilariously simple: just add the three sides together! The commenters are making it worse by suggesting ridiculous formulas like "0.25 x 4 x perimeter" (which is just the perimeter) and "pi multiplied by radius of the triangle" (triangles don't even have radii!). The real tragedy? Even with gamma-irradiated super-brain, basic geometry remains his kryptonite. Guess smashing buildings is easier than passing 3rd grade math!

The mathematical crime scene we never wanted to witness! A right triangle with sides labeled "i" and "1" while a circle just floats nearby with "NOT TO SCALE" written at the top. The hypotenuse would be √(1+i²) = √(1+(-1)) = √0 = 0... which means this triangle shouldn't even exist! It's the geometry equivalent of dividing by zero. Whoever drew this clearly wants to watch mathematicians have nervous breakdowns. No wonder they're an ex-friend - this is a friendship-ending equation. The lonely circle is just there to witness the mathematical atrocity.

Mathematicians having a collective breakdown right now! This "new triangle" with angles of 30°, 60°, 90°, and 180° totals to 360° instead of the mandatory 180° for triangles. It's literally a square trying to identify as a triangle. The geometry police are on their way with protractors drawn. Next thing you know, circles will claim they have corners too!

Behold, the revolutionary "line triangle" - where geometry goes to die! Someone clearly missed the memo that triangles need, you know, actual angles that add up to 180°. Instead, we've got a straight line with three labeled points pretending to be a shape. This is what happens when you do math after pulling an all-nighter. Next breakthrough: discovering that a circle is just a very ambitious dot. The Nobel committee remains unimpressed.

The triangle with all 3s is basically every mathematician's fever dream. It's the mythical equilateral triangle where all angles are 60° (adding up to 180°) AND all sides equal 3 units. The beauty of this simple sketch is that it represents mathematical perfection—symmetry so pure it brings tears to geometry teachers' eyes. Next time someone asks you what heaven looks like, just draw this bad boy. Pure triangular bliss.

The mathematical burn is STRONG with this one! This person's perfectly straight hairline forms a textbook right angle that would make Pythagoras himself shed a tear of geometric joy. For those who slept through math class, the Pythagorean theorem (A² + B² = C²) describes the relationship between the three sides of a right triangle. This hairline is so precisely angular that it could literally be used as a teaching aid! Whoever styled this clearly graduated from the School of Trigonometric Tonsorial Arts with honors. Remember kids, choose your barber wisely or you might become an involuntary math demonstration!

STOP THE PRESSES! Mathematicians have gone completely rogue with this "new triangle" featuring angles of 30°, 60°, 90°, and 180°! The absolute AUDACITY to create a square and call it a triangle! This is what happens when geometry rebels against its own rules! Next thing you know, circles will identify as hexagons and parallel lines will start intersecting just for the drama. The sum of angles in a triangle is supposed to be 180° but this bad boy is flaunting a whopping 360° like it's no big deal. Geometry teachers everywhere are having existential crises right now!
