In a three-quarter turn, there are three right angles. A right angle measures 90 degrees, so in a full turn (360 degrees), there are four right angles. Therefore, in a three-quarter turn (270 degrees), there are three right angles, as each right angle is 90 degrees.
The right angle of a right-angle triangle, like all right angles, is 90 degrees or one quarter of 360 (a full circle). All the angles of any triangle will add up to 180 degrees.
A right angle is 900, so 2700 make three right angles.
If a triangular based pyramid has any right angles it has three. (Think of the corner of a cube). There are many triangular based pyramids that do not have any right angles.

a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
89 well all triangles have three sides so there are three angles
270 degrees
462 * * * * * It can have three.
