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.

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: 3 equal sides and 3 equal angles Isosceles: 2 equal sides and 2 equal angles Right angle: a 90 degree angle and 2 acute angles and sides that vary in length Obtuse: an obtuse angle and 2 acute angles and sides that vary in length Scalene: 3 acute angles and 3 different side lengths

an isosceles triangle

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.

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

No. The two sides that are acute can form and angle that could be larger than or equal to 90 degrees.

any parallelogram that doesn't have a right angle in it

there are only two 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.

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
