Desmos Tool for 50b#1
3-50 b #1: Is it possible?
Is it possible to make a second triangle with two sides proportional to 3 cm and 4 cm, and an included angle of 120° that is not similar?
3-50 b #2: Is it possible?
3-50 b #2 Is it possible?
Is it possible to make a second triangle with two sides proportional to 3 cm and 4 cm, and an included angle of 120° that is not similar?
SAS: Is it possible for two triangles with proportional sides and included congruent angles to not be similar?
Is it possible to move points D & F to create a [math]\triangle[/math]DEF that is [b]not similar[/b] to [math]\triangle[/math]ABC
1-51a #1
Answer the following 2 questions about the two triangles above:
3-51 a #1
Are the triangles above similar? If so, then write [b]a similarity statement [/b]for them in the space below; if not, write 'not similar'
1-51a #2
Explain how your team arrived at the previous answer. Try to use one of our three [b]similarity conditions[/b], AA , SSS & SAS, to justify your answer.
3-51 b.
Answer the following 2 questions about the two triangles above:
3-51 b #1
Are the triangles above similar? If so, then write a [b]similarity statement[/b] for them in the space below; if not, write 'not similar'
3-51 b #2
Explain how your team arrived at the previous answer. Try to use one of our three [b]similarity conditions[/b], AA , SSS & SAS, to justify your answer.
3-51 c. #1
Answer the following 2 questions about the two triangles above:
3-51 c. #1
Are the triangles above similar? If so, then write a [b]similarity statement[/b] for them in the space below; if not, write 'not similar'
3-51 c. #2
Explain how your team arrived at the previous answer. Try to use one of our three [b]similarity conditions[/b], AA , SSS & SAS, to justify your answer.
