A triangle has three internal angles and three external angles, for a total of six angles.
3 vertices
If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.
180 interior and 360 exterior
Two angles are equal in an isosceles triangle.
Isosceles has two congruent angles.
A isosceles triangle can have two equal angles, but an equilateral triangle is actually a special isosceles triangle, so it could also have 3.
An isosceles triangle has two equal angles in the base.
three * * * * * Actually, it is 2 ******* Actually it is 3 because an equilateral triangle is a special isosceles triangle, and they have 3 equal angles
There are 3 angles in an isosceles triangle and 2 of them are equal in size. The 3 interior angles add up to 180 degrees.
If it is an equilateral triangle then it will have 3 equal angles If it is an isosceles triangle then it will have 2 equal angles plus another different size angle
There are 3 angles in an isosceles triangle and they add up to 180 degrees Two of the angles are of equal measurement
It has 2 equal base angles
2 equal sides and 2 equal angles.
An isosceles triangle has 3 sides two of which are of equal lengths it also has 3 interior angles two of which are of equal sizes.
In an isosceles triangle, two of the angles are the same.
