There are four.
There are 4 right angles in a revolution.
1 revolution = 360o 1 right angle = 90o Thus 360o ÷ 90o = 4 right angles in one revolution.
four
Four of them because 4*90 = 360 degrees which is a full revolution
In one complete revolution, there are four right angles (90 degrees each), corresponding to the four quadrants in a circle. Therefore, in two revolutions, there are a total of eight right angles.
4 since 90x 4=360 degrees
4 right angles, no other angles.
It has 6 angles, none of which are right angles.
0 right angles
A regular hexagon as no right angles. An irregular hexagon could have from none to as many as five right angles.
a tetrahedron has 3 Right angles
12 right angles.
