WebIn summary, two right angles each measure 90 degrees, and the total angle measure of two right angles is 180 degrees. This is because a straight line, which forms an angle of 180 degrees, can be divided into two right angles. 2. Facts about right angles. Properties: A right angle has several important properties. WebThe total sum of the angles in the four triangles is 4 • 180° = 720°. The sum of the angles at the center is 360 degrees (a full circle). The interior angles sum to 360 degrees (or 720° – 360°). This shows that a quadrilateral has 360 degrees in its angles. A five-sided polygon: Five triangles are formed.
WebDodecagon: 12 Sides. Not to be confused with a decagon, a dodecagon has just two more sides for a total of 12. 12 sides and 12 angles make this shape unique from the others. As you can see, the name is very similar to "decagon" which has 10 sides. The "do" prefix just means add 2 to 10 which gives you 12.
