Apex in regards to geometry means the peak or the climax such as the top of a triangle. It is not a frequently used term, with the exception of a crossword clue.
If by sperical triangle you mean a triangle on the surface of a sphere, you will need 3 dimensional coordinate geometry. Whether you use polar coordinates or linear coordinates will depend on what you want to "solve".
Pythagoras
In Euclidean plane geometry every triangle MUST BE coplanar.
yes
Trapezoid and triangle are geometry terms. They begin with T.
In geometry, magnitude is the length of the hypotenuse of a right triangle.
A right triangle in geometry is a triangle that has 90 degrees as one of its angles.
There are hundreds of terms associated with Geometry. A list of sixteen Geometry terms starting with just the letter P are Pythagorean theorem, Pi, pyramid, polygon, parabola, polytope, points, planes, projective geometry, platonic solids, parallel, power center, pedal triangle, prototile, polyhedron, and pseudosphere.
The altitude of a triangle IS a geometric concept so it intersects geometry in its very existence.
An angle less than 90 degrees.
Answer #1:Yes.=======================Answer #2:False!=======================Answer #3:Without a definition of terms, it's hard to say. Outside ofan ophthalmologist's or an obstetrician's shop, "dilating"doesn't mean much. Certainly not in geometry.
No, never in plane geometry.
