He number of 90° angles formed by the intersections of and the two parallel lines and is .

Answers

Answer 1
Answer:

Answer:

When you will draw two parallel lines , and a Transversal cutting it

The Transversal may cut the parallel lines in two ways

(a)The Transversal may be perpendicular to two lines

(b) The Transversal may cut the two parallel lines which are not perpendicular.

In both the cases , 8 angles will be formed and sum of all the angles will be 720°.

When you will consider case a , there will be exactly 8 right angles.

When you will consider case b, there will be no angle equal to 90°, but sum of total angle is 720°, which will be equal to 8 right angles.
Answer 2
Answer: A line perpendicular to the two parallel lines would create 8 right angles.

Segment VU is 2 units and segment VꞌUꞌ is 4units.Which scale factor was used to dilate figure TUVW to produce similar figure TꞌUꞌVꞌWꞌ?

Answers

In the figure the segment both VU and V'U' are horizontal, so the segment VU was scaled by a factor of 2 to dilate it and get the segment V'U'.

You can check that the same factor was used for all the segments to obtain a similar figure.
