Hey there,

Your question states: <span>Four points are always coplanar if . . .

Your correct answer from the questions above would be </span>they lie in the same place

The definition of the word $\boxed{coplanar}$ means : In the same place.

So . .Four points are always coplanar if <span>they lie in the same place.

Hope this helps many.

Craig made a mobile using geometric shapes including triangles shaped as shown. For what value of X and Y can you use a triangle

PolarNik [594]

Answer:

x = 3

y = 8

Step-by-step explanation:

In the given triangle FGH,

m∠F + m∠G + m∠H = 180° [Triangle sum theorem]

60° + 90° + m∠H = 180°

m∠H = 30°

If the given triangles FGH and TUV are congruent, their corresponding sides will be equal in measure.

m∠F = m∠T

7y + 4 = 60°

7y = 56

y = 8

GH ≅ UV

8x - 12 = 12

8x = 24

x = 3
