Draw

Using the definitions, draw in the medians of this triangle and find the centroid.

Learning Targets:
•By the end of the lesson, I will be able to define the
median and centroid of triangles.

•By the end of the lesson, I will be able to solve
problems by applying the Centroid Theorem.

Multiple Choice

In $$\Delta ABC$$ , Q is the centroid and BE=9. Find BQ and QE. Show your working out in your book.

• BQ = 6

  QE = 3

• BQ = 3

  QE = 6

• BQ = 9

  QE = 3

• BQ =3

  QE = 9
