Uholy trojuholníka
Môžu tieto uhly tvoriť trojuholník?
\( α = 60°,β = 60° \) a \( \large \gamma = 60\degree \)
\( α + β + γ = 60° +\ 60° +\ 50° =\ 170° \)
\( \normalsize170\degree=180\degree \)
\( α + β + γ = 60° +\ 60° +\ 40° =\ 160° \)
\( \normalsize160\degree=180\degree \)
\( α + β + γ = 60° +\ 60° +\ 70° =\ 190° \)
\( \normalsize190\degree=180\degree \)
\( α + β + γ = 60° +\ 60° +\ 60° =\ 180° \)
\( \normalsize180\degree=180\degree \)
