Übung Dreiecke und Kongruenz

a) a = 8 cm ; b = 4 cm ; c = 3 cm

b) a = 5 cm ; b = 6 cm ; c = 4 cm

c) $\alpha$ = 89° ; $\beta$ = 51° cm ; $\gamma$ = 50°

d) $\alpha$ = 100° ; a = 9 cm ; b = 12 cm

a) c = b' ; $\alpha$ = ${\gamma }^{\prime }$ ; $\beta$ = ${\alpha }^{\prime }$

b) b = b' ; a = c'; $\gamma$ = ${\alpha }^{\prime }$

c) b = a' ; $\alpha$ = ${\gamma }^{\prime }$; $\gamma$ = ${\alpha }^{\prime }$
