What does not have 4 sides all sides are equal all angles are acute?
An equilateral triangle.
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
Is there a triangle with 3 acute angles?
Yes. An equilateral triangle has 3 equal sides and as such, has 3 angles that are less than 90 degrees, or acute angles. Also, an isosceles triangle which has at least 2 equal sides can have a third side that is shorter than the two equal sides, creating a triangle with 3 acute angles. However, if the third side is made longer than the 2 equal sides, one angle becomes greater than 90 degrees, or obtuse. So, all equilateral triangles are have 3 acute angles, but only some isosceles triangles have 3 acute angles, those having one side shorter than the two equal sides.
What are the measures of the acute angles in an isosceles right triangle?
isosceles means that it has 2 equal sides. The 2 acute angles are 45 and 45.
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.
