ELI5: how to find the area of a right triangle
// explanation
What is the area of a right triangle?
The area is how much space is inside the triangle. [1] A right triangle is a triangle with one corner that makes a perfect square corner (90 degrees), like the corner of a book. [1]
What's the easy trick to find it?
You just need to find the two sides that make that square corner—these are called the base and height. [3] Then multiply them together and divide by 2. [2]
Can you show me an example?
If one side is 10 and the other side is 7, you do 10 × 7 = 70, then divide by 2 to get 35 square units. [2] It's like if you had a rectangle with those same sides, the triangle would be exactly half of it! [1]
Why do we divide by 2?
Because a triangle is half of a rectangle—if you took two identical triangles and put them together, they'd make a rectangle. [1][2]
