It's a triangle.
a right angle has 3 angles on it please.
a 3 sided shape is a right angle triangle
About 2/3 the size of a right angle
It looks like 3/4 of the area of a circle and it is called a reflex angle
cheesse
vertices with edges maybe a quadrilateral with 4 sides or known as a polygon has more than 3 or more sides also a right angle thats ALWAYS 90 degrees
A Triangle~!
a triangle
I can't show you the exact image but it will be 90/3= 30 degrees which is also an acute angle.
it just doesnt exist. parallelogram is a closed shape vth opposite sides parallel adjacent angle not 90 degree. triangle is closed shape vth 3 sides.
The angle of rotational symmetry for a shape with an order of 3 is calculated by dividing 360 degrees by the order. Therefore, 360 degrees ÷ 3 equals 120 degrees. This means the shape can be rotated by 120 degrees, 240 degrees, or 360 degrees (which brings it back to the original position) and still look the same.
What about the other angle(s). You need at least 3 sides and 3 angles to make a closed figure.
