Midsegment of a triangle, step by step

Join the midpoints of two sides of a triangle and the segment you draw is parallel to the third side and exactly half its length.

The question
12x cm

The midsegment

midsegment=half the base
12× 2=24
x=24 cm
  1. A midsegment joins the midpoints of two sides, and it is half the length of the third side — so the base is always twice the midsegment.
  2. The midsegment is 12 cm, so the base is twice it: 12 × 2 = 24.
  3. So x = 24 cm.

How it works.

  1. 01

    A midsegment joins the midpoints of two sides, and it is half the length of the third side — so the base is always twice the midsegment.

  2. 02

    The midsegment is 12 cm, so the base is twice it: 12 × 2 = 24.

  3. 03

    So x = 24 cm.
