## Acute Triangle meaning

An acute triangle is defined as a triangle in which all of the angles are less than 90°. In other words, all of the angle in an acute triangle space acute.

## properties of Acute triangle

All equilateral triangles space acute triangles. An equilateral triangle has three sides of same length and three equal angles of 60°.An acute triangle has three enrolled squares. Every square corresponds with a part of a triangle side. The other two vertices of a square are on the two continuing to be sides of the acute triangle.Any triangle in i beg your pardon the Euler line is parallel come one next is one acute triangle.Acute triangles have the right to be isosceles, equilateral, or scalene.The longest side of one acute triangle is opposite the largest angle.## Acute angle Formulas

In an acute triangle, the adhering to is true because that the size of the sides:

a2 + b2 > c2, b2 + c2 > a2, c2 + a2 > b2

If C is the biggest angle and also hc is the altitude native vertex C, climate the adhering to relation because that altitude is true for an acute triangle:

1/hc2 2 + 1/b2

For an acute tirangle v angles A, B, and also C:

cos2 A + cos2 B + cos2 C
