They both have 3 sides but an isosceles triangle has two equal sides whereas an acute triangle with different acute angles has no equal sides and is said to be a scalene triangle, or an acute triangle with three equal acute angles (of 60° each) and three equal sides is called an equilateral triangle.

Any triangle that has three equals sides must have three acute angles and is equilateral.

An equilateral triangle.

It is an equilateral triangle

An equilateral triangle which has three sides of equal length also has three equal angles. Each angle measures 60° and is therefore an acute angle as it is less than 90° .

An equilateral triangle which has three sides of equal length also has three equal angles. Each angle measures 60° and is therefore an acute angle as it is less than 90° .

Equilateral: equal sides and angles(60 degrees) Isosceles: two equal sides and angles Scalene: no equal sides or angles right triangle: has a 90 degree angle in it obtuse triangle: has an obtuse angle in it acute triangle: is made up of all acute angles

Sides aren't acute, angles are. A triangle with three acute angles would be called (appropriately enough) an acute triangle.

The word acute refers to angles, not sides. It does have all three angles are acute (less than 90Â°)

This is a SCALENE triangle. There several types of triangle; Equilateral ; The three sides are the same length and the three angles are ALL 60 degrees. All angles are ACUTE Isosceles ; Two sides are the same length , and two angles have the same degree value. . May be ACUTE or OBTUSE. Right angled ; The three sides may vary in length, but ONE angle is 90 degrees. Is ACUTE, and maybe ISOSCELES. Scalene ; All three sides are of different length, and all three angles have different degree value. May be ACUTE or OBTUSE. Fort ALL triangles , of whatever shape, the sum of the interior angles is ALWAYS 180 degrees.

An isoceles triangle has at least two sides equal; an equilateral has three sides equal so it is also isoceles; and since all angles are acute it is also an acute traingle
