Calculator for Right Angles and Hypotenuse

A right triangle is fully defined by just two of its measurements. Enter any two known values, such as sides or angles, into the calculator below and it will instantly calculate everything else: the hypotenuse, both acute angles, the altitude from the right angle to the hypotenuse, area, perimeter, and the radii of both the inscribed and circumscribed circles.

Trail Walking with a Say's Phoebe

 

A bird that appears to be a Say's Phoebe was jumping from fence post to fence post ahead of me and Joie while we walked, until it finally flew onto a nearby bush, on a Mid-Spring morning. It kind of seemed like they wanted us to follow, but maybe they were just keeping an eye out for any bugs we might stir up as we walked along the trail, a behavior for which Flycatchers are known.
