# rectilinear

«rectilinear» in Mova's school dictionary: **Made of straight lines** — its meaning for a pupil, its sense in the lessons and examples.

### part of speech

adjective (rectilinear)

### meaning for a pupil

1) Made of straight lines. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/R/rectilinear/#m1)

2) Moving in a straight line. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/R/rectilinear/#m2)

3) (maths) A rectilinear shape has only straight sides, often with right angles, like an L-shape or a rectangle. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/R/rectilinear/#m3)

### sense in the lessons

In maths it describes compound shapes made of rectangles, for example «find the area of this rectilinear shape» — you split it into rectangles and add the areas. In science «rectilinear motion» is movement in a straight line. It tells the reader that there are no curves. Phrases: «rectilinear shape», «rectilinear figure», «rectilinear motion».

### examples

- Draw a rectilinear shape with six sides. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/R/rectilinear/#x7)

### note

Formal and mostly a maths word. Comes from Latin «rectus» (straight) + «linea» (line). Maths problems: to find the area, split into rectangles and add; for the perimeter, add every side, and work out missing sides by subtracting lengths. It does not mean «rectangle» only.
