Ffocws dysgu

Dysga ddefnyddio sgiliau geometreg i adnabod a thynnu llinellau perpendicwlar a pharalel.

Mae'r wers hon yn cynnwys:

• un fideo
• dau weithgaredd

Lesson content

Learn to use geometry skills to recognise and draw perpendicular and parallel lines.

This lesson includes:

• one video
• two activities

Wedi ei chreu mewn partneriaeth â .

Mae llinellau paralel bob amser yr un pellter ar wahân ar eu hyd cyfan. Mae llinellau perpendicwlar yn croesi ei gilydd ar ongl sgwâr.

Parallel lines are always the same distance apart for their entire length. Perpendicular lines cross each other at right angles.

Fideo / Video

Y gwahaniaeth rhwng llinellau paralel a pherpendicwlar.

The difference between parallel and perpendicular lines.

Nodiadau i rieni

Ar ôl gwylio'r fideo, bydd disgyblion yn gallu:

• deall bod llinellau paralel yn aros yr un pellter ar wahân, a fyddan nhw byth yn croesi
• deall bod llinellau perpendicwlar yn croesi ar ongl sgwâr
• deall sut i adnabod llinellau perpendicwlar a pharalel

Notes for parents

After watching the video, students will be able to:

• understand that parallel lines always stay the same distance apart, and that they never cross each other
• understand that perpendicular lines cross at a right angle
• understand how to recognise perpendicular and parallel lines

Gweithgaredd 1 / Activity 1

Labela’r ddau fath o linell.

Label both types of line.

Gweithgaredd 2 / Activity 2
