In the fig., AB||CD, AO/OC= BO/OD =1/2, and AB= 5cm. DC=?
(a)
In rt. ∆IJK, if ∠JLI = 90, then
IJ² = IL*IK
JK² = LK*IK
IK² = (IK-LK)*IK + (IK-IL)*IK
All of the above
In the fig., AX, BY, CZ are lines from the vertices of the triangle ABC, to the respective opposite sides, and are concurrent. (BX/XC)*(CY/YA)*(AZ/ZB) =
0
1
(BX/XC)²
AZ/2
If EG = 1/2 EF, ∠DHE = 90, then what is DE² + DF² =?
2(DG² + EG²)
2(DG² + DF²)
2{DG² + (EF²/4)}
Both A and C
P and Q are points o the sides AC and BC respectively of ∆ABC (right-angled at C). The relation between the sides AQ, BP, AB, PQ is
AQ + BP= 2(AB² +PQ²)
AQ² +BP² + BP= √(AB² +PQ²)
AQ*BP= √(AB² +PQ²)
AQ² +BP² = (AB² +PQ²)
In a rt.∆ , a perpendicular p is drawn from the right angle to the hypotenuse, dividing the hypotenuse into 2 parts x,y. If rectangles are formed on the respective segments of ∆, the relation between x,y,p is
√p = x+y
p²=x/y
√p = x/y
p²=xy
