4th Grade Math 10.4, Classify Quadrilaterals

A polygon is a closed two-dimensional shape formed by three or more straight sides that are line segments. A quadrilateral is any polygon with four sides and four angles. We can name a quadrilateral by the vertices of its angles, with capital letters. We label them clockwise or counter-clockwise in order. Tick marks on line segments show they have the same length. They show us the sides that are equivalent. We discuss trapezoid, parallelogram, rhombus, rectangle, square, and kite. Rectangles and squares are the only quadrilaterals with right angles. The word Quadrilateral means four sides. We classify different shapes by putting them into their correct column. A dimension is a measurement of length, width, or height. A two-dimensional figure (2D) has two of these measures, length and width. A three-dimensional figure (3D) has all three measures, length, width, and height. We have a Venn diagram of quadrilaterals classifying them as a trapezoid, parallelogram, rectangle, rhombus, or square. 4th Grade Math 10.1, Lines, Rays, and Angles https://youtu.be/EzdoXfoz0d0 4th Grade Math 10.2, Classify Triangles by Angles https://youtu.be/o2rfDufQi8Q 4th Grade Math 10.3, Parallel Lines & Perpendicular Lines https://youtu.be/2sdlKeenLLw 4th Grade Math Playlist https://www.youtube.com/playlist?list=PLKi4WTp6PRGX7RhcxctRibNb7V091JZfn I'm using the Houghton Mifflin Go Math! 2015 copyright textbook for this playlist.
