Question

To prove that triangle Xwy is parallel to triangle DEC, which additional information is needed?

a) The lengths of the sides of triangle Xwy
b) The measures of the angles in triangle Xwy
c) The lengths of the sides of triangle DEC
d) The measures of the angles in triangle DEC

Answer 1

To prove that triangle Xwy is parallel to triangle DEC, we need to know the measures of the angles in triangle DEC.

Step-by-step explanation:

To prove that triangle Xwy is parallel to triangle DEC, the additional information needed is d) The measures of the angles in triangle DEC.

To determine if two triangles are parallel, you need to compare their corresponding angles. If the corresponding angles are equal, then the triangles are parallel.

Therefore, we need to know the measures of the angles in triangle DEC in order to determine if it is parallel to triangle Xwy.
