التشابه:المستقيمات المتوازية والأجزاء المتناسبة - حل مسائل2

The video tutorial addresses a geometry problem involving the determination of whether two line segments, DE and GH, are parallel. The instructor guides through checking proportionality between segments by calculating and comparing the ratios of DG to GF and EH to HF. The conclusion is drawn that the segments are not parallel as the ratios do not match.

What is the main question being addressed in the video?

• Whether DE is longer than GH

• Whether DE is equal to GH

• Whether DE is parallel to GH

• Whether DE is perpendicular to GH

What method is used to determine if two lines are parallel?

• Checking if they are the same length

• Checking proportionality of corresponding sides

• Checking if they intersect

• Checking if they are perpendicular

What is the ratio of DG to GF given in the video?

• 3 to 5

• 2 to 3

• 1 to 3

• 1 to 2

What is the simplified ratio of EH to HF?

• 5 to 6

• 3 to 5

• 2 to 3

• 1 to 2

What conclusion is drawn about the lines DE and GH?

• They are parallel

• They are perpendicular

• They are equal in length

• They are not parallel
