Question

MN is the midsegment of △ ABC.
Find BC if MN = 17 cm.

hintHint:

Use the property of a midsegment in a triangle and find out.

The correct answer is: Hence the length of BC = 34 cm.


    Complete step by step solution:
    A midsegment of a triangle is a segment that connects the midpoints of two sides of
    a triangle. Its length is always half the length of the 3rd side of the triangle.
    From this property, we have  MNequals 1 half B C

    not stretchy rightwards double arrow 17 equals 1 half B C

     not stretchy rightwards double arrow B C equals 17 cross times 2
    not stretchy rightwards double arrow B C equals 34 cm
    Hence the length of B C equals 34 cm.
