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° .

What are all the three triangles called?
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
What is the difference between an isosceles and acute triangle?
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.
What is a angle that measure 60 degrees?
Form an equilateral triangle - this is where all three sides are of equal length and all three internal angles are equal. well its less that 90 degrees so its an acute angle
What triangle has 3 acute angles and 3 equal sides?
Any triangle that has three equals sides must have three acute angles and is equilateral.
What triangle has three equal sides and three acute angles?
An equilateral triangle.
Can a right triangle have three acute angles and three equal sides?
No, a right angled triangle cannot have three acute angles because an acute angle is less than 90 degrees and a right angled triangle has one angle of exactly 90 degrees (which is what right angled means, equal to 90 degrees).Also, because the triangle has a right angle (of 90 degrees) it cannot have three equal sides; it can have two equal sides but the side opposite to the right angle (the hypotenuse) will always be longer than either of the other two sides.
What is the difference between an equilateral triangle and an acute triangle?
An acute triangle leans to the right but an equilateral triangle is wide and straight. An acute angle has three inside angles all of which are smaller than 90 degrees, which adds up to 180 degrees of course, and the sides are not necessarily equal. An equilateral triangle has three sides which are equal and each inside angle = 60 degrees (that is all three of them are the same angle automatically). Sides are equal or angles are equal = equilateral triangle.

What is a angle that measure 60 degrees?
Form an equilateral triangle - this is where all three sides are of equal length and all three internal angles are equal. well its less that 90 degrees so its an acute angle
What are three attributes of a rhombus?
It is a 4 equal sided quadrilateral It has 2 equal opposite acute and 2 equal opposite obtuse angle Its opposite sides are parallel
Is an scalene triangle an obtuse or an right triangle?
A scalene has three sides of unequal lengths, and all threes angles different.The largest angle defines the triangle¹:acute: a scalene triangle could have sides 6, 9, 10right angle: a scalene triangle could have sides 6, 8, 10obtuse: a scalene triangle could have sides 6, 7, 10So a scalene triangle could be any of acute, right angle or obtuse.¹In terms of acute, right angle or obtuse. Triangles can also be defined in terms of their sides: equilateral (all three sides equal), isosceles (two sides equals) or scalene (no sides equal)
What are the classification of triangle according to measure?
Equilateral: All angles of a triangle are 60 degrees, they are all equal. Right: One angle is 90 degrees (right angle), the other 2 are acute. Acute: All three angle are acute (less than 90 degrees). Obtuse: One obtuse (greater than 90 degrees) angle. Isosceles: Two sides of equal lenght, 2 equal angles. Scalene: No sides of equal length, angles are all different in size.
Which triangle has 3 acute angles and 2 equal sides?
An acute isosceles triangle has three acute angles (
What triangle has 3 acute angles and 3 equal sides?
Any triangle that has three equals sides must have three acute angles and is equilateral.
What triangle has three equal sides and three acute angles?
An equilateral triangle.
Two types of triangle?
There are three main types of triangle:Scalene - all angles are different and all sides are different lengthsIsosceles - Two sides are equal in length and the two angles (between the third side and the two sides of equal length) are equalEquilateral - All three angles are equal (at 60°) and all three sides are of equal length.If all angles are less than 90° then the triangle can also be described as an Acute triangle; an equilateral triangle is acute by definition as all angles are 60° which is less than 90°.A Scalene or Isosceles triangle can also be described as a Right angle triangle if one angle is 90° (a right angle); in the isosceles triangle this is the angle between the sides of equal length.A Scalene or Isosceles triangle can also be described as an Obtuse triangle if one angle is greater than 90°; in the isosceles triangle this is the angle between the sides of equal length.
