A Geologist needs to know a lot about geometry.
We call it a circle.

point of intersection
Intersection. Another name for it is the vertex.
hypotenuse
Such a point is called the orthocenter. Even the fact that all three altitudes intersect at a point is quite interesting because only two lines are guaranteed to intersect at a point, but we have three.

Theorems are statements in geometry that require proof.
Two dimensions. :)
It is a perpendicular line that forms a right angle at the point of intersection.
