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
