Given : two parallel lines at a distance of 5cm. Base line as 6cm..
To find : . Draw two different triangles on the same base and between the same parallels.
Solution:
1. Draw a line XY
2. Take two points B and C on XY such that BC = 6 cm
3. Draw right angles at B & C using set square / protractor and take 5 cm length and mark points E & F
4. Draw a line PQ passing through E& F
PQ || XY
taking point A on PQ
join AB & AC
Draw AD ⊥ BC
Area of triangle ABC = (1/2) BC * AD
Take another point M on EF
draw MN ⊥ BC
Area of triangle MBC = (1/2) BC * MN
AD = MN Hence Area of triangle ABC = Area of triangle MBC
