Lin knows that angle A is congruent to angle D. She claims that triangles ABC and DEF must be similar. Convince Lin that the triangles are not similar.

In order to determine similarity between two triangles, you need at least 2 angles to be congruent. If only 1 angle is congruent, the triangles are not similar. This is true because if 2 of the angles are congruent, then the remaining angle must be congruent also.

E.g. ∠A and ∠D both equal 90°, but ∠B and ∠C = 45°. While, ∠E = 30° and ∠F = 60°.  

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
