Test your understanding of Quadrilaterals with these NaN questions. Quadrilaterals only have one side more than triangles, but this opens up an entire new world with a huge variety of quadrilateral types. Learn about it here.
Transformations in math involve changing a shape's position or which way the shape points. There are three main types: translations (moving the shape), rotations (turning the shape), and reflections (flipping the shape like a mirror image). Rigid transformations keep the shape's size and angles the same.

- No.A transformation includes rotations, reflection, and translations. Translations just slide the figure around the grid.
- Nice question! A common type of non-rigid transformation is a dilation. A dilation is a similarity transformation that changes the size but not the...
- A side of a polygon is a type of line segment. Any line segment has infinitely many points, though its length is finite. Note that for any two dist...
- A *translation* (or "slide") is one type of transformation. In a translation, each point in a figure moves the same distance in the same direction....
- Dilations are not a rigid transformations. For something to be a rigid transformation, angles and side lengths need to stay the same. Dilations inc...
- There are 3 main types of rotations: 1.) 90∘ clockwise - To move a point or shape 90∘ clockwise, simply use this equation: (x, y) → (y, −x). 2.) 90...
- In most geometry courses this is taught early into the semester.
- I have that problem, too. But you only need to figure out how many degrees does the shape looking have. It needs more experience to do it.
- A dilation in math is an operation which make a shape that is smaller than the parent shape. Hope this helps!!
- It seems so. I believe any shape in the Euclidean space can make a rigid transformation.

A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles. There are two main types: concave and convex. There are also various subcategories of convex quadrilaterals, such as trapezoids, parallelograms, rectangles, rhombi, and squares. Created by Sal Khan. Questions.

- Yes, they have to be closed. In fact, all polygons have to be closed.
- The area formula for a Rhombus is: A = (1/2) (d1) (d2) d1 & d2 represent the length of the 2 diagonals
- the rhombus is a slanted square and the parallelogram is a slanted rectangle. they both are quadrilateral. The term 'quadrilateral' means 4 sides....
- A rectangle has 4 straight sides and 4 right angles. A rhombus must have opposite equal angles and 4 equal sides. A square has 2 sets of opposite r...
- Yes, all polygons are defined as closed figures.
- Even though you may think there is another parallel side for each side in a regular hexagon, the definition of a parallelogram is a four-sided plan...
- Yes. All squares are both rectangles and rhombi.
- not necessarily. the weird pink shape that he showed did not have equal sides
- So you start with a parallelogram, two pairs of parallel sides, opposite sides are congruent, adjacent angles are supplementary, diagonals bisect e...
Jan 14, 2023 · Quadrilaterals are a special type of polygon. As with triangles and other polygons, quadrilaterals have special properties and can be classified by characteristics of their angles and sides. Understanding the properties of different quadrilaterals can help you in solving problems that involve this type of polygon.
Aug 24, 2021 · Why can’t the triangles “squish” the way a quadrilateral (and other shapes) can? Here’s one way to understand it. Imagine you pick two of your three lengths and lay them on top of each other, hinged at one corner.
Properties. A quadrilateral has: four sides (edges) four vertices (corners) interior angles that add to 360 degrees: Try drawing a quadrilateral, and measure the angles. They should add to 360°. Types of Quadrilaterals. There are special types of quadrilateral: Some types are also included in the definition of other types!
