The figure below shows parallel lines cut by a transversal: which statement is true about ∠7 and ∠8? 1. ∠7 and ∠8 are supplementary because they are a pair of corresponding angles. 2. ∠7 and ∠8 are complementary because they are a pair of adjacent angles on a straight line. 3. ∠7 and ∠8 are congruent because they are a pair of adjacent angles on a straight line. 4. ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

Option 4.

Step-by-step explanation:

When two adjacent angles are formed at a point on a line so that sum of their measures is 180°, angles are called as supplementary to each other.

In the figure attached, ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

Option 4. is the right answer.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
