ALL triangles - have internal angles that add up to 180 degrees.
Any type of triangle will have angles that add up to 180o. yet two angles of an isosceles triangle are equal
A quadrilateral shape has four sides and four internal angles. A triangle has three sides and three internal angles. Therefore there is no such thing as a quadrilateral triangle.
Sum of angles in a triangle is 180
The 3 interior angles of a triangle add up to 180 degrees
The internal angles add to 180 degrees.
The internal angles of any triangle add up to 180 degrees.
The internal angles of a triangle always add up to 180 degrees.
No, the internal angles of a triangle add up to 180 degrees
It has 4 and they add up to 360 degrees
The 3 internal angles of any triangle add up to 180 degrees
All triangles have 3 internal angles. If drawn on a flat plane (that is redundant, but you could imagine a triangle on a sphere or some other shape) the internal angles will add to 180 degrees. In an equilateral triangle all three internal angles are equal.
If you mean the internal angles, No. The 3 internal angles of any triangle will and must add up to 180 degrees.
Yes they have to
The 3 inside angles of any triangle add up to 180 degrees
Yes. An acute triangle has three angles that individually are less than 90 degrees. Remember you can add the internal angles together in a triangle and they will always add up to 180 degrees.
If you're referring to the internal angles of a triangle - the missing angle would be 30 degrees. Remember - in a flat triangle - the internal angles always add up to 180. Therefore - add up the angles you know, then subtract that from 180.
