there are three angles on an isosceles triangle
An acute scalene triangle has none. An acute isosceles triangle has one and an [acute] equilateral has three.
It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).
3
One acute angle
There is 180 degrees in every triangle.
3 lines * * * * * None if it is acute angled scalene One if it is acute angled isosceles and Three if it is equilateral.
there is 1 line of simmetry An equilateral triangle has three. An acute isosceles has one and an acute scalene has none.
There are many different types of triangles. A few are a right triangle, obtuse triangle, equilateral triangle, acute triangle and isosceles triangle.
Im assuming your question is How many acute angles does the isosceles triangle has. It should have 2
None. If there was a right angle then it would not be called an acute triangle.
