Just watch. We know the formula for a right-angled triangle is its base x height, but..why? This animation explains the reason why. Questions? Read Notes and Credits.
Questions you Probably Have: Q1: Why did you make a scratch project related to math? You usually make Splatoon content. A1: I decided to make math projects so I could get more followers. Q2: I don't understand what's happening in the animation can you explain? A2: Okay, so a right angled triangle is half a square. So the formula for the area of a right angled triangle is half of the formula of the area for the square. The formula for the area of a square is side x side, so the formula for the area of a right angled triangle is: (SIDE x SIDE)/2 Q3: If the two sides aren't equal, can we still use this formula? A3: Yes! As long as it is half the area of a square or a rectangle (rectangle is allowed because it has the same formula as the square). Q4: Why did you make the title specifically "right-angled triangle"? A4: Not all triangles have the same formula like an equilateral triangle. The formula won't work because it is not half of a square or a rectangle.
