Haley constructed the acute isosceles triangle LMN as shown in the figure below.

Question

anonymous · Answer

What is the error in Haley’s construction?

She did not ensure that the length of LM is different from the length of LN.

She did not plot more than one point on the arc.

She plotted vertices to the right of the perpendicular line.

She did not ensure that length of MN is different from the lengths of the other two sides.

hint : isosceles triangle must have two equal sides

anonymous · Answer

so it would be this one She did not ensure that length of MN is different from the lengths of the other two sides. ??

think again hmm

anonymous · Answer

this one She plotted vertices to the right of the perpendicular line.

ganeshie8 · Answer

no.

every point on arc is at equal distance from center, remember ?

ganeshie8 · Answer

its a semicircle, so if you draw two points on arc, and form a triangle with center, it would be isosceles for sure.

anonymous · Answer

its this one She did not plot more than one point on the arc.

ganeshie8 · Answer

yes ! :)

yw :) and i knw you just doing hit n trial.. just remember circle definition and isosceles triangle. you would be good to answer these, good luck :)
