Solve sufficient side, angle, area or perimeter inputs and inspect a uniformly scaled right triangle, its angles and hypotenuse altitude.
01 / PURPOSE-SPECIFIC INPUTS
02 / RESULT & INTERACTIVE INSPECTION
The diagram uses a single uniform geometric scale. Extremely skinny triangles may be hard to inspect; the text values retain the computed dimensions. This is geometry arithmetic, not a construction design specification.
Side a: 3 units. Right-angle marker is at the meeting of legs a and b.

Use two legs, hypotenuse and either leg, one side with acute angle alpha, area and leg a, or perimeter and leg a. Each mode requests a sufficient pair rather than accepting arbitrary contradictory extra inputs.
Solve sufficient side, angle, area or perimeter inputs and inspect a uniformly scaled right triangle, its angles and hypotenuse altitude. Inspect the calculated data through labeled controls and review worked assumptions before using a result.

Use two legs, hypotenuse and either leg, one side with acute angle alpha, area and leg a, or perimeter and leg a. Each mode requests a sufficient pair rather than accepting arbitrary contradictory extra inputs.
Legs 3 and 4 give hypotenuse 5, area 6, perimeter 12 and altitude to the hypotenuse 12/5 = 2.4, all in the corresponding common side units.
Alpha is opposite leg a and beta is opposite leg b. Therefore sin alpha = a/c, cos alpha = b/c and tan alpha = a/b. Angles must be strictly acute; numeric degrees and radians are supported.
With known area K and leg a, b = 2K/a. With perimeter P, set s = P − a, then b = (s² − a²)/(2s), requiring P greater than 2a.
The two axes share one geometric length scale, preserving the actual aspect ratio. A right-angle marker and optional hypotenuse altitude are drawn, although extremely skinny features may be smaller than a pixel.
No. All sides use one common selected unit, and area uses that unit squared. The label is explicit reference information rather than an independent per-side conversion. Use the Unit Converter for measurement conversion.
