Now we will see what does a 45 degree angle look like?

The 45 degree angle is just like an Acute Angle.

An angle whose measure is less than 90 degree or less than radian or angle lies in between 0 to 90 degree is known as acute angle. Now we see some of the types of angle-

Acute angle, Right angle, Obtuse angle, Straight angle, Reflex angle and Full angle;

Now we have small introduction about the angles.

If the angle is less than 90 degrees then the angle is said to be an acute angle. If the angle is exactly 90 degree then the angle is known as Right Angle. If the angle is more than 90 degree and less than 180 degree then the angle is said to be Obtuse Angle. If the angle is exactly 180 degree then the angle is said to be straight angle. If the angle is more than 180 degree and less than 60 degree than the angle is said to be reflex angle. If the angle is exactly 360 degree then the angle is said to be full angle.

Now some parts of an angle:

The corner Point in the given angle is said to be a vertex of an angle. The angles lie between the two lines, the line is known as arms.

We can say that the geometric figure which is obtained by the two lines. The angle which is equal to the perimeter of a Circle is full angles. Its value is 360 degree or 2⊼.

An acute triangle can also be a Scalene Triangle because all the sides and angles of a scalene triangle are unequal.
