How many diagonals does a 20 sided shape have?

A 20 sided shape has 209 diagonals i worked it out by drawing a table and split it into 4 colunms. I named the first one Name of polygon and the second one Number of sides the next one, Angle at centre and the last one Diagonals. I started with a Triangle which has 3 sides and its angle at centre is 120 degrees but, it doesn't have any diagonals so i put 0. Next i used a quadrilateral which has 4 sides and its angle at centre is 90 degrees and, it does have diagonals it has 2. Afterthat i put down a pentagon which has 5 sides its angle at centre is 72 degrees and it has 5 diagonals. I kept the process going so i put down Hexagon, Heptagon, Octagon, Nonagon and finally Decagon when, i had finished filling in the rest this was my results:Hexagon= Had 6 sides its angle at centre 60 degrees and its diagonals 9Heptagon= Had 7 sides its angle at centre 51.5 degrees and its diagonals 14Octagon= Had 8 sides its angle at centre 45 degrees and its diagonals 20Nonagon= Had 9 sides its angle at centre 40 degrees and its diagonals 27Decagon= Had 10 sides its angle at centre 36 degrees and its diagonals 35this is my results just for DiagonalsTriangle=0Quadrilateral=2Pentagon=5Hexagon=9Heptagon=14Octagon=20Nonagon=27Decagon=35Can you see a pattern?well i can see a pattern that adds a different number every time which is:it adds 2it adds 3it adds 4it adds 5it adds 6it adds 7it adds 8it adds 9so for a 20 sided shape you need to take 35 and add on 10 etc to 20. This is my results:35 + 9 = 4444 + 10 = 5454 + 11 = 6565 + 12 = 7777 + 13 = 9090 + 14 = 104104 + 15 = 119119 + 16 = 135135 + 17 = 152152 + 18 = 170170 + 19 = 189189 + 20 = 209So the answer is 209 diagonals on a 20 sided shape :-P

Which shape fits the description below A three-sided figure with one acute angle one right angle and one obtuse angle.?

A three sided shape is a triangle but the given angles are incorrect because a triangle can't possibly have a right angle and an obtuse angle because its 3 interior angles must add up to 180 degrees.

What is the exterior and interior angle of a shape with 12 sides?

If this shape is a regular 12-sided polygon, then the sum of its angles is 1,800 degrees [(n -2)180]. So the measure of one angle is 150 degrees (1,800/12), and the exterior angle is 30 degrees (180 - 150).
