Types of Angles Definition
Acute angle: The angle which is less than 90 degree is an acute angle. For instance, we can say 45 degree is an acute angle.
Right angle: The angle which is equal to 90 degree is right angle.
Obtuse angle: The angle which is greater than 90 degree is an obtuse angle. For instance, we can say 75 degree is an obtuse angle. I have recently faced lot of problem while learning cbse 10th sample papers sa2, But thank to online resources of math which helped me to learn myself easily on net.
Ascending order: Arranging a list of given elements from smallest number to greatest number.
Consider, the given list of numbers are 9,4,8,2 then the ascending order of a given list is
2,4,8,9.
Descending order:
Arranging a list of given elements from greatest number to smallest number.
Consider, the given set of numbers is 9,4,8,2 then the descending order of a given list is 9,8,4,2.
Twice:
Twice means two times.
The twice of 4 is 2 times of 4 that is 8.
