Question

What is the name for an angle which looks like letter L?
A.Acute angle
B.Obtuse angle
C.Right angle
D.None of these

Answer 1

Hint: In order to find the angle of the given letter, make a diagram of the letter and consider the vertical part to be perpendicular and horizontal part to be base. Then from the properties of the angle, decide which type of angle best suits the letter.

Complete answer:
We are given a letter L. We need to find which kind of angle correctly defines the letter.
Considering the horizontal part of the letter L to be base and the vertical part to be perpendicular.

Describing the options:
A.Acute angle: An angle which is less than ${90^ \circ }$ or we can say who’s perpendicular and base makes an angle less than ${90^ \circ }$. But the letter L does not satisfy the properties to be an acute angle. So, Option A is not correct.
B.Obtuse angle: An angle which is more than ${90^ \circ }$ or we can say who’s perpendicular and base makes an angle more than ${90^ \circ }$. But the letter L does not satisfy the properties to be an obtuse angle. So, Option B is also not correct.
C.Right angle: An angle which is exactly ${90^ \circ }$ or we can say who’s perpendicular and base are perpendicular to each other and makes an angle equal to ${90^ \circ }$. And the letter L satisfies the property to be a right angle. So, Option C is correct.
Therefore, the letter L forms a right angle and Option C is correct.

Note:
1.There are various types of angles like reflex angles, straight angles, etc. but the main three types of angles used in calculations are Obtuse, acute and right angles.
2.There are more letters in English Alphabets which form right angles, some of them are: E, H, I, T.
