Geometry is a branch of mathematics that deals with the size, shape, and relative position of physical elements. Geometry also deals with the properties of space. Geometry looks at the length, width, height, and space of an object.
in geometry, perimeter is the length around the outside of an object.
It means height
Thales of Miletus is credited with being one of the first to apply deductive reasoning to geometry. He calculated the height of the pyramids in Egypt by using the length of their shadows and the concept of similar triangles. By measuring the shadow of a nearby object of known height at the same time, he was able to determine the height of the pyramids proportionally. This method showcased his innovative approach to mathematics and geometry.
On the Cartesian plane points have coordinates of length and height
In geometry, a regular object has all sides and all angles equal.
Altitude in geometry means perpendicular height.
pencil
The space within an object is its volume.
