180 degrees
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
First, an acute angle is an Angle that is less than a right angle (<90°) Secondly, an obtuse angle is one that is more than a right angle but less then a straight angle (<180°) then, the complementary angles of a pair of angles is 90° or a Right angle and the complement of an acute angle is the amount needed of an unknown angle (against known angles) to make 90° or a right angle a supplementary angle are a pair of angles which, when Added together, make 180° or a straight line. and the suplement to an angle is the value of an unknow angle to to be added on to make 180°
How many of these 30° angles will fit together to make a straight line?
No? Wouldn't they then be supplementary? Opposite rays make a straight angle/line, and if the exterior sides made the straight angle, the adjacent angles would be supplementary. ...Right?
The compliment.
Any two angles that total 90 degrees will make up a right angle. Two 45 degree angles will make a right angle - 90 degrees. Also an angle of 30 degrees and another angle of 60 degrees will make up a right angle.
A zero angle or a straight angle.
An angle is like acute angle, right angle, and obtuse angle. It takes 4 right angles 2 make a square. So no an angle is not like a square.
A right angle is 900, so 2700 make three right angles.
One angle must be 90o, which is the right angle. The sum of the other two angles must equal 90o.
Right triangles have two acute angles, but that doesn't make them right. Having a right angle makes them right.
you cannot make a regular shape which has 3 right angles only, you will always end up with 4 right angles
