Answer:
It has reflectional symmetry with four lines of symmetry. It has no rotational symmetry It has point symmetry. It has rotational symmetry with an angle of rotation of 90°.
I believe its 2. 4*2=8. 2*7=14. 2*10=20
15 has prime factors of 5,3
21 has prime factors of 7,3
35 has prime factors of 7,5
105 has prime factors of 7,5,3
315 has prime factors of 7,5,3,3
hope this helps
Answer:
D) (-2, -3)(-4, -3)(-2, -9); because corresponding pairs of sides and corresponding pairs of angles are congruent
Step-by-step explanation:
For triangles to be congruent, it is not enough that corresponding angles are congruent. In addition, there must be at least one pair of corresponding sides that are congruent. (Then all pairs will be congruent.)
The points listed in choices B and D are points that form a right triangle with leg lengths 2 and 6. However, choice B only refers to the angle measures, and not the sides. Choice D is the correct one.
2/5 , i dont have an explanation but maybe try that! I just did the math on paper
