None.
Infinite angles. If you are referring to degrees then the answer is 360, but if the question is angles I can get as many angles as I want inside a circle.
A triangle has three internal angles and three external angles, for a total of six angles.
There are many angles inside a circle. You have inscribed angles, right angles, and central angles. These angles are formed from using chords, secants, and tangents.
10 sides and 10 angles
a tetrahedron has 3 Right angles
A tetrahedron has four vertices.
All the angles in a tetrahedron are 60 degrees.
It has four vertices.
It has twelve angles but all of them need not be acute.
Four.Four.Four.Four.

It need not have any eg in a tetrahedron.
None because a tetrahedron is a triangular based pyramid which has 4 faces, 6 edges and 4 vertices.
No. A right angle would be 90 degrees; a tetrahedron is composed of four equilateral triangles, which by definition have equal angles of 60 degrees apiece.* * * * *Wrong!A tetrahedron is a solid shape enclosed by any four triangles. Only a regular tetrahedron that requires equilateral triangles. So an ordinary tetrahedron can have right angles - up to 3 of them at one vertex.
A tetrahedron.
None because a tetrahedron is a triangular based pyramid with 4 faces, 6 edges and 4 vertices
