What is an acute equilateral triangle?
An equilateral triangle must be acute because each angle is equal to 60 degrees. If all three angles are less than 90 degrees then a triangle is acute.
If angle 3 is actue what is the other angles?
The question appears to relate to the angles of a triangle. 1) If angle 3 is acute then the other two angles can also be acute. In the case of an equilateral triangle all three angles are equal and acute. 2) If angle 3 is acute and one other angle is obtuse then the remaining angle is acute. 3) If angle 3 is acute and one other angle is a right angle then the remaining angle is acute.
Does a triangle have a right acute and obtuse angle?
Yes . Triangle have right acute and obtuse angle except compelete angle.
How do you classify a triangle by the sizes of there angles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- Right angle triangle:a 90 degree angle and 2 acute angles Scalene triangle: 3 acute angles Obtuse triangle: an obtuse angle and 2 acute angles Isosceles triangle: 2 equal base angles and an apex angle Equilateral triangle: 3 equal angles each measuring 60 degrees
What is the measure of the interior angle of an equilateral triangle?
Each of the interior angles of an equilateral triangle is 120 degrees.
