1) In triangle ADE, BC is parallel to DE. Ar of triangle ABC = 25 sq.cm, ar of trapezium BCED = 24 sq.cm and DE = 14 cm. Calculate the length of BC. (this I found to be 10 cm). Also find the area of triangle BCD. ( I am stuck here).
2) In a trapezium ABCD, AB is parallel to DC and diagonals AC and BD intersect at point P. If AP : CP = 3 : 5, find : a) triangle APB : triangle CPB (b) triangle DPC : triangle APB (c) triangle ADP : triangle APB (d) triangle APB : triangle ADB.
Find the coordinates of the points which trisect the line segment joining the points P (4, 2, –6) and Q (10, –16, 6).This is an exercise question(ex 12.3,Q-5)couldn't we do the same problem like this:
if it is a trisect then first we can find the mid point of PQ,say R
And then wouldn't the midpoint of R&P,R&Q be the points required????
find the distance of the point P(-4,3,5) from the coordinate axes.
