A right angle triangle, a square and a rectangle are some of them.
Right angles are formed when perpendicular lines meet each other.
A right triangle
A parallelogram with at least one right angle
A triangle and any irregular polygon with 4 or more sides can have some angles that are lass than right angle.
All triangles that are not right triangles.
a right angle is a right angle
A right angle is typically identified by a small square symbol placed at the vertex of the angle. This square indicates that the angle measures exactly 90 degrees, distinguishing it from acute and obtuse angles. In diagrams, this representation helps to clearly denote right angles in geometric figures.
Because a right angle is a right angle.
A right angle is an angle of 90 degrees.
Assuming your question is what makes a right-angle, it is an angle of 90o .
A right angle is a angle with 90o
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
because a right angle is right and a left angle is wrong
