An equilateral triangle has three acute (60 degree) angles.
No. An acute triangle has to have three acute angles. A right triangle has to have one 90 degree angle.
If none of the three angles of a triangle is ninety degrees, then it is not a right triangle
no. A triangle has total 180 degrees. An equilateral triangle requires all three angle measures to be the same, so every angle HAS to be equal to 60 degrees. A right triangle has 1 90 degree angle and 2 45 degree angles, so it can never be an equilateral triangle.
A right(-angled) triangle
37 degree
The sum of the three interior angles of a triangle is always 180 degree is known as angle sum property of a triangle.
An equilateral triangle has three acute (60 degree) angles.
No. In an equilateral triangle all three angles are the same - 60º
No. An acute triangle has to have three acute angles. A right triangle has to have one 90 degree angle.
If none of the three angles of a triangle is ninety degrees, then it is not a right triangle
no. A triangle has total 180 degrees. An equilateral triangle requires all three angle measures to be the same, so every angle HAS to be equal to 60 degrees. A right triangle has 1 90 degree angle and 2 45 degree angles, so it can never be an equilateral triangle.
100 degree, 40 degree and 40 degree.
Unless it is a religious triangle it does not have to have any angels! Seriously, though, a triangle does not have to have a 90 degree angle. In terms of its angles, the only requirement is that the measures of the three angles adds to 180 degrees (or pi radians).
A right(-angled) triangle
Every one of the three sides.
-- An 'acute triangle' is a triangle in which each of the three interior angles is an acute angle. -- Each of the three interior angles in every equilateral triangle is a 60-degree angle. -- Any angle of less than 90 degrees is an acute angle. -- It sure looks like every equilateral triangle does fit the definition of 'acute triangle'.
