WebNov 18, 2024 · A right triangle is a special case of a scalene triangle, in which one leg is the height when the second leg is the base, so the equation gets simplified to: area = a × b / 2. For example, if we know only the right triangle area and the length of the leg a, we can derive the equation for the other sides: b = 2 × area / a WebRight-angled triangles are always scalene or isosceles, and they are your focus today.

WebWell, the key here to realize is if you know two interior angles of a triangle you can always figure out the third because the three need to add up to 180 degrees. So if this is 40 and that is 50, these two add up to 90. So to add up to 180 degrees, this one must be a 90-degree angle. We can even mark it as a right angle.
