Acute Angle - Definition with Examples
What is Acute Angle?
Types of Angles
There are three basic types of angles; right angle, acute angle, obtuse angle.
Definition of an acute angle:
An acute angle is an angle that measures less than 90 degrees.
∠ABC measures 30 ̊and hence it is an acute angle
A triangle formed by all angles measuring less than 90˚ is also known as an acute triangle. For example, in an equilateral triangle, all three angles measure 60˚, making it an acute triangle.
Dividing the right angle will give us two or more acute angles since each newly formed angle will be less than 90˚.
Two acute angles formed by dividing the right angle
Some real-life examples of acute angles are:
If we slice a pizza into 5 or more slices, each slice of pizza will make an acute angle.
Each slice of the pizza makes an acute angle.
Another example is the wall clock. The arms of a wall clock make acute angles at several hours of a day. For example, 2 o’ Clock.
The hour hand and the minute hand forming an acute angle at 2 o’ Clock.
