Is all acute triangles similar?
Only if they have the same angles
Is it true that all triangles have at least 2 acute angles?
Yes. The total degrees of the 3 angles in a triangle must equal 180, so it's not possible to have a triangle with 2 angles >= 90.
What are three ways to classify a triangles by its angles?
The three kinds of triangles are:right triangle :one of the angles is a right angle (i.e. measures 90 degrees)acute: All of the angles measures less than 90 degrees. A special case of acute isthe equiangular or equilateral triangle in which all angles measure 60 degrees;obtuse: One of the angles measure more than 90 degrees.
What is the definition to acute triangle?
A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.
Is a triangle 180 degrees or 360 degrees?
Triangles whether acute, obtuse, equilateral or scalene will only ever have angles that add to 180 degrees.
