Property 13
1.
\(\text{ABC equilateral triangle}\)
\(\Rightarrow\alpha=?\)
2.
\(\text{ABCD Square}\)
\(\text{EDC equilateral triangle}\)
\(\Rightarrow\alpha=?\)
3.
\(\Rightarrow\alpha=?\)
Property 14
\(m\left(\widehat{BAE}\right)=m\left(\widehat{EAC}\right)\)
\(\Rightarrow\alpha=\samefrac{m\left(\widehat B\right)-m\left(\widehat C\right)}2\)
1.
\(m\left(\widehat{BAE}\right)=m\left(\widehat{EAC}\right)\)
\(\Rightarrow\alpha=?\)
2.
\(m\left(\widehat{BAE}\right)=m\left(\widehat{EAC}\right)\)
\(\Rightarrow\alpha=?\)
3.
\(m\left(\widehat{BAE}\right)=m\left(\widehat{EAC}\right)\)
\(\Rightarrow\alpha=?\)
