Geometry.
It is geometry.

It started off as a study of triangles and is a study of straight lines and angles, as well as relationships between them.
Geometry is all about the study of angles, lines, planes, and shapes
Because trigonometry is concerned with the lines (their lengths) and angles between lines. The latter requires knowledge about their direction.

Perpendicular lines meet at right angles
Angles are the points at which lines meet. Sides are the opposite, being the lines that connect at angles.
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
It is called coordinated geometry which is plotted on the Cartesian plane.
A line that crosses two lines in the same plane at two different points is called a transversal. Transversals can create various angles with the lines they intersect, leading to relationships such as corresponding angles, alternate interior angles, and consecutive interior angles. These relationships are key in geometry, particularly in the study of parallel lines and angle relationships.
