All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.
Equaliateral Triangles have all three sides and angles (60 degrees)equal Isosceles Triangles have to equal sides and angles Scalene Triangles have no equal sides or angles
They're similar triangles.
some triangles and rhombuses. trapoziods do not have acute angles it has obtuse angles. :)
They have three sides and three angles
there is many ways to write when classifying a triangle, you can classify it by its sides or angles. When you classify it by angles you can classify it by acute, obtuse, and right triangle. when classyfing it by sides its isosceles, equilateral, and scalene!
all sides + angles the same = equilateral one side + angle the same = isosceles all sides and angles different = scalene
You can classify triangles by:Whether one of their angles is greater than 90 degrees, equal to 90 degrees, or all angles are less than 90 degreesWhether they have two or three congruent angles (equivalent to having two or three congruent sides)I think that's about it.
degree dumb as
Classification of triangles by their sides:equilateral = 3 sides are equalisosceles = 2 sides are equalscalene =no equal sideClassification of triangles by their angles:acute = the 3 angles are less less than 90 degreesright = it has an angle which is 90 degreesobtuse = it has an angle which is more than 90 degrees
Similar triangles don't just have proportional angles, they have IDENTICAL angles!
Isoceles triangles and right triangles have 2 corresponding equal angles three equal corresponding angles are equilateral triangle
1 triangle = 3 angles. 8 triangles = 8*3 = 24 angles!
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
isosceles -2 equal sides, 1 other length side, 2 equal angles, 1 other angle scalene -all angles and sides different equilateral -all sides and angles same (angles always 60degrees)
you classify triangles by seeing the sides as if the triangle was isosceles, equilateral, or scalene Isosceles= two angles equal or two sides equal Equilateral= all angles equal and all sides equal Scalene= all angles different and all sides different. ☻☻ I HOPE IT HELPED☻☻
