Does an acute angle have three equal sides?
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° .
Is an equilateral angle also an acute angle?
There is no such thing as an equilateral angle. Equilateral refers to a shape whose sides are of equal length. The lengths of the sides of an angle are indeterminate.
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
Are isosceles triangles always acute triangles?
No. The two sides that are acute can form and angle that could be larger than or equal to 90 degrees.
How do you classify a triangle according to their angles and according to their sides?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classified as follows:- Scalene has 3 acute angles of different sizes and different sides Right has a 90 degree angle and 2 acute angles with 2 sides being perpendicular Obtuse has an obtuse angle and 2 different acute angles and different sides Isosceles has has 2 equal angles and an apex angle and 2 equal sides Equilateral has 3 equal angles each being 60 degrees and 3 equal sides Acute angle is greater than 0 but less than 90 degrees Right angle is 90 degrees Obtuse angle is greater than 90 but less than 180 degrees
What is acute angle and isoseles angle?
acute angle is an angle that is less that 90 degrees. An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.
Does an acute angle have three equal sides?
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° .
How many sides are equal an acute angle?
2
What triangle has one acute angle and two equal sides?
an isosceles triangle
Is an equilateral angle also an acute angle?

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 are the characteristics of the different types of triangles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are graded as follows:- Scalene triangle has 3 different acute angle Right angle triangle has a 90 degree angle and 2 acute angles Obtuse triangle has 1 obtuse angle and 2 acute angles Equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees Isosceles triangle has 2 equal sides and 2 equal base angles
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.
Are isosceles triangles always acute triangles?
No. The two sides that are acute can form and angle that could be larger than or equal to 90 degrees.
What has two parallel sides two obtuse and acute angles and its opposite sides are equal?
any parallelogram that doesn't have a right angle in it
