The answer is D. Bc the DEF Triangle is basically the reflection
Naya [18.7K]3 years ago
3 0

Answer:

D. reflection across a vertical line

Step-by-step explanation:

Reflection is basically a mirror image. Since you can see that the first triangle is flipped over to get the second one, this is a reflection.

It is not a vertical translation; this means that the triangle shifted up or down.

It is not a horizontal translation, this means that the triangle shifted left or right.

It is not a rotation about point A either, this would have meant that the triangle spun around.

A triangle with 7,?, and form a right triangle.
Vlad1618 [11]

9514 1404 393

Answer:

  C  24

  D  25

Step-by-step explanation:

Consider the choices offered:

  5 and 7 will not form a triangle* with any of the other lengths

  7 and 12 will not form a triangle with any of the other (longer) lengths

  7 and 24 will form a triangle with the other possibilities, 25 and 29. (needs further consideration)

  7 and 25 will not form a right triangle with 29, because a right triangle cannot have 3 odd-length sides.

__

<em>Further consideration</em>

  7^2 +24^2 = 49 +576 = 625 = 25^2 . . . . checking Pythagorean theorem

The side measures 7, 24, 25 will form a right triangle.

_____

* A triangle can be formed from three segments only if the sum of the shortest two exceeds the length of the longest one.

Plz help I dont understand this at all
ANEK [815]
1) the sum of all three angles in a triangle is always 180, so number 5 is w=80

2)I assume they mean x. since the x angle and the 70 angle are a linear pair they must add to 180, so x has to be 110

3) the top 60 angle makes a vertical angles with the angle right below it. since vertical angles are congruent, the angle below has to be 60 also. again all 3 must add to 180 so o is also 60

4) these are all linear pairs. every angle shown has to be 90
