Isosceles triangle 1 2 2

Basic Geometry

The 3 edge lengths are:

• e₁ : $ 1 $ ≈ 1.000
• e₂ : $ 2 $ ≈ 2.000
• e₃ : $ 2 $ ≈ 2.000

The 3 angles are:

• α₁ : $ \arccos{\left (\frac{1}{4} \right )} $ ≈ 75.5225°
• α₂ : $ \arccos{\left (\frac{1}{4} \right )} $ ≈ 75.5225°
• α₃ : $ - 2 \arccos{\left (\frac{1}{4} \right )} + \pi $ ≈ 28.9550°

Further Properties

Dihedral angles:

• Minimal concave angle: 75.0000°
• Minimal convex angle: 75.0000°

Reversed edges: None
