A triangle has three internal angles and three external angles, for a total of six angles.
Yes. The total degrees of the 3 angles in a triangle must equal 180, so it's not possible to have a triangle with 2 angles >= 90.
An EQUILATERAL Triangle. An ISOSCELES Triangle is two equal sides and two equal angles. A RIGHT-ANGLED Triangle has ONE right angle (90 degrees) A SCALENE Triangle has neither equal sides nor equal angles.
By Definition, a triangle with two Congruent Sides is an Isosceles Triangle. For ALL angles to be Acute, that is, LESS than 90o , the two opposite angles must be greater than 45o. Remember that the SUM of the angles in a Triangle must equal 180o.
All angles of a triangle total to 180 degrees.

a triangle has 3 angles that total 180 degrees
A triangle has three internal angles and three external angles, for a total of six angles.
All triangles have a total of 180 degrees for interior angles in Euclidean plane geometry
there are 360 in a square and 180 in a triangle
Sum of interior angles of a triangle total 180 degrees
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
180 degree.
All triangles have a total sum of 180 degrees interior angles.
The total sum of all angles in a triangle is 180o . The individual angles may differ, but they can only add up to 180o
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
