Why doesn't the polygons triangle and quadrilateral end in gon?
Their names had been in use before the -gon names came around. Their names had been in use before the -gon names came around. Their names had been in use before the -gon names came around. Their names had been in use before the -gon names came around.
What are all the names you can use rectangle?
parallelogram hope i help you :) Well, I think it is a parallelogram, square, rhombus. That is all I know :P
How do you use geomitry words to describe how to join triangles to make quadrilaterals?
Any 2 congruent triangles joined together will form a 4 sided quadrilateral
What quadrilateral have two different pairs of equal sides?
The 3 properties of shapes that we are going to look at are # The number of sides # The interior angles (the angles inside). # The length of the sides. These properties help use to remember which shapes are which and why they so called (in some cases). Let us look at shapes that have 4 sides Quadrilaterals (Quad- means 4). Quadrilaterals ALWAYS have 4 sides The interior angles of a triangle add up to 360 degrees. Here are the quadrilaterals you are expected to know about. # Square # Rhombus # Rectangle # Parallelogram # Trapezium # Kite That does not seem to many does it. Let us look at the properties of quadrilaterals.
Do you calculate the interior angles of regular and irregular polygons the same way using the number of sides - 2 times 180 degrees n-2180 sum of interior angles. A Pentagon would 5-2?
All triangles have 180 degrees, all quadrilaterals have 360 degrees, no matter what the kind of triangle or quadrilateral. The formula would hold true for all polygons. Prove this by drawing diagonal lines in a polygon (do not cross one diagonal with another) to divide the polygon into quadrilaterals and/or triangles. Then add the degrees in the quadrilaterals and triangles in your polygon. This should give you the correct number of degrees. If you have a many sided polygon, it is necessary to use the formula, because the figure would be very difficult to draw. Formula- Number of sides minus 2, times 180 degrees. (n-2) X 180= degrees in a polygon
