How do you get the radius of circle inside the triangle?
For an equilateral triangle where the width of each side is given as w and each angle is 60 degrees:r = SquareRoot(w^2 - 0.25w^2)For an isosceles triangle with two angles a and a side between them of length b.r = 0.5 * b * tan(0.5 * a)
What is an isosles triangle?
An isosceles triangle is a triangle with 2 congruent sides and 2 congruent angles.
What is a issociales triangle?
An isosceles triangle is a triangle with 2 congruent sides. (2 sides are the same length)
The angles that are inside of a shape?
What about them? It depends on the shape! All 2 dimentional shapes are made of triangles. A triangle has a total of 180 degrees inside. A square is simply 2 triangle side by side therefore totaling 360 degrees inside. (180+180). Penticon 3 triangles hence 540 degrees. This will continue for every side added to a shape then add 180 degrees. This will look good on your maths exam (Formilure (No of sides -2)x180=total degrees)
What do you call a triangle with 2 sides and 2 angles that are congruent?
An Isosceles Triangle.
