Since the definition of an equilateral triangle is "a triangle with three equal sides", it must therefore also have three equal angles. Since the angles in any triangle add up to 180 degrees, each of those angles is 60 degrees.
The interior angles of a triangle add up to 180. So a triangle with 3 equal sides (or angles) will have 60-degree angles. * * * * * True, but the question is about an isosceles triangle, not an equilateral triangle. The angles of an isosceles triangle are x, x and 180-2x degree where x is a measure between 0 and 90 degrees.
All Triangles add up to 180 degrees, no matter if it is Right or Scalene or ANY TRIANGLE!! If it does not, it is not a triangle!
There are 3 angles in a triangle and they add up to 180 degrees
ANY triangle MUST add up to 180 degrees.
The sum of the 3 exterior angles of an equilateral triangle add up 360 degrees
An equilateral triangle has 3 equal inside angles that add up to 180 degrees.
180 degrees
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
An equilateral triangle has 3 equal sides and 3 equal interior angles that add up to 180 degrees.
The 3 interior angles of 60 degrees add up to 180 degrees
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
An equilateral triangle has 3 equal sides and 3 equal 60 interior angles that add up to 180 degrees
Interior angles of all triangles add up to 180 degrees.
No-An equilateral triangle has equal angles, an obtuse angle is greater than 90. So, an equilateral triangle with an obtuse angle would have the three angles add up to a MINIMUM of 270.0000000000001, and a triangle's angles must add up to 180°.
An equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees that all add up to 180 degrees.
Three angle and three sides that are closed is a triangle. interior angles add up to 180 exterior anglis add up to 900
