Let’s go through each pair of lines one by one. We need to decide if they are:
-
Parallel → lines that never meet, always the same distance apart (like train tracks).
-
Perpendicular → lines that cross at a perfect right angle (90 degrees — like the corner of a square).
-
Intersecting → lines that cross each other, but NOT at a right angle.
We’ll look at each box from left to right, top to bottom.
---
Box 1 (top left):
Two slanted lines going in the same direction, never touching.
→ They’re parallel.
Box 2 (top middle):
Two lines crossing each other, forming an “X”. The angles don’t look like 90 degrees.
→ Intersecting.
Box 3 (top right):
Two lines crossing, and there’s a little square mark where they meet — that means it’s a right angle!
→ Perpendicular.
Box 4 (middle left):
Lines crossing, no right angle symbol, and the angles look sharp or wide — not 90°.
→ Intersecting.
Box 5 (middle middle):
One line is almost vertical, one is horizontal — they form a T-shape with a right angle (you can see the small square).
→ Perpendicular.
Box 6 (middle right):
Two slanted lines, same slope, never meeting.
→ Parallel.
Box 7 (bottom left):
Lines crossing, and again — there’s a little square showing a right angle.
→ Perpendicular.
Box 8 (bottom middle):
Two straight up-and-down lines, side by side, never touching.
→ Parallel.
Box 9 (bottom right):
Two lines starting near each other and going off in slightly different directions — they will eventually meet if extended. Not parallel, not perpendicular.
→ Intersecting.

Final Answer:
Top row: Parallel, Intersecting, Perpendicular
Middle row: Intersecting, Perpendicular, Parallel
Bottom row: Perpendicular, Parallel, Intersecting
Parent Tip: Review the logic above to help your child master the concept of parallel intersecting and perpendicular lines worksheet.
