WebScalene Triangle. No equal sides. No equal angles. How to remember? Alphabetically they go 3, 2, none: Equilateral: "equal" -lateral (lateral means side) so they have all equal sides. Isosceles: means "equal legs", and … WebAngles triangles geometry formulas clarify the connection. And these connections are accurate for every triangle. The side opposite to the largest angle is the largest in the triangle. In addition to that, the side opposite to the smallest angle is the smallest. Finally, the mid-sized side and mid-sized angles are opposite to each other.

WebAltitude (h) = ( 2 × A r e a) / b. For a triangle ∆ A B C, the area is 81 c m 2 with a base length of 9 c m. Find the altitude length for this triangle. Solution: Here we are given the area and base for the triangle ∆ A B C. So we can directly apply the general formula to find the length of altitude.
