YOU can use a right angle by making it small to make it acute or you can make it big so it is obtuse
So basically , you have an right angle and another angle . You draw an right angle over the angle your looking at and if its smaller than the right angle then its an acute angle . If its bigger than the right angle then its a obtuse angle . GoodLuck!(;
90o angle
Right angle E. The vertex of any angle can also be used to name the angle.
A right angle is 90 degrees if an angle is wider than 90 it is obtuse if it is less than 90 it is an acute angle.
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.
Yes.
With a ray
An acute angle is smaller than a right angle.An obtuse angle is larger than a right angle.^_^
Another right angle.
So basically , you have an right angle and another angle . You draw an right angle over the angle your looking at and if its smaller than the right angle then its an acute angle . If its bigger than the right angle then its a obtuse angle . GoodLuck!(;
If the other angle is smaller than the right angle, it is an acute angle.If the other angle is the same as the right angle, it is a right angle.If the other angle is bigger than the right angle but smaller than two right angles, it is an obtuse angle.If the other angle is the same as two right angles, it is a straight angle.If the other angle is bigger than two right angle but smaller than four right angles, it is a reflex angle.After four right angles, the other angle starts back at being an acute angle.
Equilateral, isosceles, scalene and right angle triangles.
A right angle is a 90 degrees angle
If a triangle has a right angle, it is a right triangle.
It is another right angle of 90 degrees because supplementary angles add up to 180 degrees.
there will be a right angle in the triangle.
If one of the angles in a triangle is exactly 90 degrees, then it is a right-angle triangle.
