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

A Triangle~!
a triangle
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
What about the other angle(s). You need at least 3 sides and 3 angles to make a closed figure.
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.
a square with 3/4 of its corners cut off
