acute triangle
A triangle with 3 acute angles
An acute triangle is a type of triangle in which all of its angles are acute angles, meaning they measure less than 90 degrees. In other words, all angles of an acute triangle are less than a right angle.
To identify if a triangle is acute or not, you need to measure all three angles of the triangle using a tool such as a protractor. If all three angles of the triangle are less than 90 degrees, the triangle is acute.
Acute triangles have some unique properties. Firstly, all sides of an acute triangle are of unequal length which implies that the triangle is scalene. Secondly, the altitudes of an acute triangle lie entirely within the triangle. Thirdly, the medians of an acute triangle are all inside the triangle and intersect at a point called the centroid.
Examples of acute triangles in real life include many musical instruments like the guitar or the violin, steep mountain peaks, and the faces of many animals such as cheetahs or wolves.
