because an isosceles triangle or any kind of triangle is 180 degrees.
The right isosceles triangle has 180 degrees as all triangles do
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
Not normally but if it has angles of 90, 45 and 45 degrees it is then both a right angle and an isosceles triangle
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
You cannot have an isosceles trinangle with 60 degrees sides
There is 180 degrees in every triangle.
The right isosceles triangle has 180 degrees as all triangles do
all triangles have 180 degrees even isosceles
180 interior and 360 exterior
a isosceles has 180 degrees
All triangles are 180 degrees.
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides/ angles.
Answer: 180 degrees. Explanation: The three angles of a triangle, regardless of type of triangle, always sum to 180 degrees.
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
a right triangle
An isosceles triangle has interior angles of 180 degrees and exterior angles of 360 degrees
It depends upon the length of the sides.
